Error 4001 Exception on Page.
by Graham,Neil [NCR] 27 Apr '06

27 Apr '06

Hi, Recently one of my pages just started generating this exception whenever we went to the page. It prevented any of the page from rendering (only the exception was on the page, nothing else) so I can't even delete the page. This is bad, but the bigger problem is that I can't search the wiki for content because when I search for terms that I know are on the old page, I get the same exception. To recover the data, I copied the content from the XWD_CONTENT column in the xwikidoc table and created a new page with the content from the database (it had information that would have been difficult to replace). The new page renders properly, the old page is still broken (see below) and the search is still broken. Does anyone know what the problem might be and how I can fix it? If I can't fix the old page, is there a way for me to delete it without having to go to the page? This is pretty important, because a lot of the terms on the old page we want to search on are very common for our project. Any help greatly appreciated! Neil Here is the exception I receive when I try to go to the old page, or if I try to search the wiki with terms I know are on the old page.

Changing the "You need to have the 'comment' right to post a comment"
by Michael Grabowski 27 Apr '06

27 Apr '06

Hello all, Is it possible to change the message users get when they do not have proper access rights i.e. "You need to have the 'comment' right to post a comment." I restrict comments from anonymous users and I'd like to remind my users that they may need to login. This would save me from answering numerous e-mails about "not being able to post comments." I'd like mine to read like this: You are unable to post a comment because either you have not registered (<-- with a link to the register page) or you are not logged in (<-- with a link to the login page). Is this a change I can make or would an admin have to make the change? Thanks in advance for the help. I appreciate it. - Michael

Blog categories - no content
by Dave Mangot 26 Apr '06

26 Apr '06

We have just installed Xwiki (0.9.840) and it was working fine, but now we have a problem. I think someone may have changed something as Admin. When I post a new News from the front page for a blog, I can choose a category. The entry shows up fine on the front page of the Xwiki. However, when I choose the blog category, there is nothing there. It's like I never made an entry. This is the URL which looks correct to me: http://my.companyname.com/xwiki/bin/view/Blog/Category?category=Marketing%2… When I click the permalink and hit edit, it shows the category as selected. I don't see anything obvious in catalina.out. How can I figure out why no blog entries show up? It doesn't matter if I'm logged in as Admin or a regular user. -Dave -- Dave Mangot Terracotta Inc. 650 Townsend St. Suite 325 San Francisco, CA 94103 USA +1 415 738 4059 dmangot(a)terracottatech.com This e-mail incorporates Terracotta's confidentiality policy, which is online at http://www.terracottatech.com/emailconfidentiality.shtml

How can I restrict a menu section?
by Adrian Hall 26 Apr '06

I have xWiki 0.9.840 up and running now. Question: I want to have optional sections of the menu bar appear when members of certain groups are logged in. For example, I'd like to have a restricted space (which I now have), but not have the link appear on the left hand menu unless the user is allowed to visit that space.

On Usability and UI
by Aldo Bucchi 26 Apr '06

26 Apr '06

Hi all, I have installed several wiki-ish/collab apps within my intranet so we can test drive them and pick one by the end of the month ( twiki, mediawiki, confluence, xwiki, jspwiki, snipsnap, sharepoint, etc ). So far xwiki is one of the best from the dev point of view. It is free, flexible ( makes for a nice platform for quick day-to-day inhoues apps ), and 100% java. And since we are all geeks, it makes for a nice toy. But from the usability POV it lags behind. * Forms and buttons are not polished ( interaction is awkward and feedback is sometimes ambigous ) * There is too much on the screen I really believe you should focus on improving the UI, as it accounts for a large part of the perceived value... take a look at twiki, confluence or SnipSnap ( and even mediakiwi and it's sound simplicity ). Is something on these lines planned for the next release? Dates? I am tweaking the templates to see how far I can go, but I'd rather stay aligned with you guys. Great work ;), Aldo -- ::::: Aldo Bucchi ::::: mobile (56) 8 429 8300

Access Control and Rights
by Adrian Hall 24 Apr '06

24 Apr '06

Hi All, I am attempting to set up a new Wiki for our Intranet running on Jboss 4.0.3SP1 with Tomcat 5.5.16 and MySQL database. I need access control with the following specs: Everyone in Admin Group gets to do anything "Admin" can. People in specific groups get to edit/add content to specific spaces Registered users get to view everything Guests get view access only to Main (and I can turn that off if necessary) I have a user XWiki.ahall (which is me) I added this user to XWiki.XWikiAdminGroup, so that group now contains XWiki.Admin and XWiki.ahall. I have other groups named (for instance) Xwiki.KBGroup to control access further. There are a whole bunch of these. In my Xwiki access rights, I have Xwiki.XWikiGlobalRights 0: Xwiki.XWikiAdminGroup -> Group: Xwiki.XWikiAdminGroup -> Permissions: view,edit,admin,comment -> Users: <blank> -> Allow/Deny: Allow 1: Xwiki.XWikiAllGroup -> Group: Xwiki.XWikiAllGroup -> Permissions: view -> Users: <blank> -> Allow/Deny: Allow 2: Xwiki.XWikiGuest -> Group: <blank> -> Permissions: view -> Users: <blank> -> Allow/Deny: Allow (this last one is what I think will allow me to turn on/off guest). Now, this, I think, will allow Xwiki.ahall the ability to edit the rights, and do other things that "Admin" can do, but it doesn't. I don't get the "Admin" menu option, and I don't get all the extra options under "More Actions" Is there something I am missing here? The reason I want to do this is so I can turn on LDAP authentication - our LDAP server doesn't have an Admin user, so I won't be able to log in as an admin after I turn LDAP Authentication on, so I need an alternate Administrator. -- Adrian Hall Sr. Product Line Manager, Administration and Identity Management e. ahall(a)mirapoint.com; t. +1 (408) 720-3856; c. +1 (408) 667-4977

[xwiki-users] Using VelocityTools 1.2 with XWiki
by Robin Fernandes 24 Apr '06

24 Apr '06

Hi all, Is it possible to get VelocityTools v1.2 working with XWiki v0.9.840? http://jakarta.apache.org/velocity/tools/generic/ In particular I'm trying to get ListTools working. I tried copying all the jars from the VelocityTools1.2 archive into the XWiki lib dir, removing the older libs, and editing the toolbox.xml as appropriate. But this must be causing incompatibilities, and results in a bunch of exceptions on startup. Cheers, Robin.

RE: [xwiki-users] #include<what?>
by THOMAS, BRIAN M (SBCSI) 24 Apr '06

24 Apr '06

Ludovic: Thanks for your explanation, which was very helpful; sorry I haven't replied before this. Looking at the source, it was clear that one directive turned on a "pre" flag and the other didn't, but the implications of this which you explained had not occurred to me, especially since the $xwiki methods that implement them also allowed a flag of the same type. However, I am already using #includeMacros, as I mentioned, so unfortunately it doesn't solve my problem. I had the issues confused in my mind, but it now appears that it doesn't have to do with which directive I use to include it, because it isn't a question of whether the included content is rendered before or after inclusion, but whether a macro definition file ever loads. Our wiki is configured as by default up to this point - i.e. the "view" action calls $xwiki.includeForm("$menudoc", false), which (If I understand it correctly) effectively includes the content of $menudoc (which is XWiki.Menu in our case) WITHOUT any interpretation. Our copy of XWiki.Menu has been modified to use #includeTopic("Main.FoldingMenu") (causing Main.FoldingMenu to be interpreted in a separate context BEFORE being inserted into the including document -- correct?). Main.FoldingMenu uses #includeMacros("Main.MenuMacro") and, after setting up the necessary stylesheets and javascript functions, calls the one macro defined in it, #doMenu, on $doc, where the top-level menu entry objects reside. When the wiki is started, the #includeMacros directive apparently fails, because the name "doMenu" is not the name of a macro definition in the context when called, so that instead of executing the macro, Velocity simply renders it as #doMenu(com.xpn.xwiki.api.Document@7a3a97). So the content of the menu document is being rendered (witness the expansion of its single argument, which was $doc), but at the time that it is, the macro definition was not in the context. After some activity ranging from just opening Main.FoldingMenu as a regular document (calling the "view" action on it) to opening it in the editor to actually saving a new version of it, the macro document finally loads and the macro executes. Friday (while I was out, naturally), none of that worked for the people who were here and they replaced it with a hard-coded list. First, it appears that I need to check the logs to see whether there was some failure in the loading of the macro document and troubleshoot that. It may be that a permission problem exists, though I doubt that this could have been the problem - first, every time the problem was corrected, the person who seems to have fixed the problem also experienced it first, and second, the history of the menu document shows that they apparently tried some manipulations of this sort without effect. Neither of these discounts the idea, of course, so neither will I, but I'm not hopeful. Meanwhile, has anyone any ideas? I will, of course, try adding the macro definition to macros.vm, but I suspect that this would only decrease the incidence of the problem rather than eliminating it. It happens seldom enough that it's hard to reproduce as it is, and can't be done at all without restarting the wiki, which is getting to be fairly popular. For one thing, is there a programmatic way to know when an #include directive fails, or do I have to examine the logs? I wouldn't argue for muddying a template language with such a feature, certainly, but if there's some background magic available to administrative users for troubleshooting purposes, it could be useful. I think there's probably still a little too much that needs server administrator access to troubleshoot. brain[sic] -----Original Message----- From: Ludovic Dubost [mailto:[email protected]] Sent: Sunday, April 09, 2006 8:48 AM To: xwiki-users(a)objectweb.org Subject: Re: [xwiki-users] #include<what?> Hi, #includeTopic -> includes and executes any code in the context of the INCLUDED document (variables are the one from the included document) #includeForm -> includes and executres any code in the context of the INCLUDING document (variables are the one from the including document) #includeMacros -> used to embed macros to solve the problem that you are having Another way to solve it is to put your macro in /templates/macros.vm and restart XWiki.

RE: [xwiki-users] SQL hair-pulling
by THOMAS, BRIAN M (SBCSI) 23 Apr '06

23 Apr '06

Frank: Thanks. Now, to refine the question a bit: is the set of columns available within each virtual table equivalent to the set of all the Velocity "properties" of each object - which means, as I understand it, all attributes represented by public methods named "get" and "set", declared locally or inherited, by the object's class? It doesn't seem that I have been able to depend on that, but I've gotten pretty turned around dealing with all the metadata and meta-metadata. It seems that the "virtual" schema is supported by the data in the documented schema, though it's not clear that everything needed is there. Further, I don't think I quite understand how to parse the returned result. From the javadoc, I can see that XWiki.search() returns a java.util.List. Through Java reflection I find that the List is actually a java.util.ArrayList, and that each ArrayList element is a java.lang.Object, which is itself an array of java.lang.Object, or depending on how I look at it, of java.lang.reflect.Field. I get the expected number of objects in the array(the number of requested fields in the query), and each one is of the expected type, with the expected value, which is great, but it doesn't seem from the analysis that it ought to. Again, I've probably just confused myself unnecessarily... The real difficulty I have is in directly addressing any field of a returned row. I can loop through it and see what each one is, but without doing that and assigning each field based on the iteration count, I can't just use each field as I can with the returned list from getObjects. I've tried using the get() method that takes an integer index, but that doesn't seem to work; among other things, there's also another get() that takes a string for the field name. I haven't tried that one... Thanks again for a clear answer; this message is both further question and open-ended comment, in hope of stimulating more discussion in order to gain a more solid understanding of what can be done. However much I love to tinker, I am not primarily a developer but an architect and designer, so I need to concentrate on making sure that the tools our developers use are up to the jobs that I give them. It does appear that XWiki is, although the metadata gymnastics needed to navigate the schema are probably a bit too tedious for the average application programmer, let alone the average wiki user. I'm seriously considering building a tool to make those queries more straightforward, though my job rarely permits such luxuries as merely improving the productivity of all our staff... Of course, I can always go to the sources, and I will if I don't get an answer here (and if I have time). More than that, I will share it with the list, on the off chance that someone else needs it... brain[sic] -----Original Message----- From: Frank Häfemeier [mailto:[email protected]] Sent: Thursday, March 23, 2006 10:39 AM To: xwiki-users(a)objectweb.org Subject: AW: [xwiki-users] SQL hair-pulling >As mentioned in an earlier message, I got into the $xwiki.search() >world yesterday, and am thoroughly confused. > >The main problem seems to be that the XWiki database schema and the >schema used in all of the $xwiki.search() queries I have found are >completely disjoint. > >Instead of the documented tables and columns, what seems to be used is >a schema which reflects the object model within XWiki.

[xwiki-users] Rare bug when creating a templated document+object from a form

Hi, When creating a new template, class based page (e.g. the FAQs), I occasionally (maybe 1 in 40-50 times) get a blank document after filling out the form and clicking save. I have seen this both on xwiki.org/xwiki.com and 2 personal 0.9.840 installations. Several other users of these installations have seen this issue too. Here's an example: http://www.xwiki.com/xwiki/bin/view/Doc/HowCanIDynamicallyEscapeOutBackslas… I created that document from the "create a new FAQ entry" form on http://www.xwiki.com/xwiki/bin/view/Doc/WebHome . I was presented with the FAQ form, which I filled out. But when I pressed Save, frustratingly it just saved a blank document. My form content was gone. No object is associated with the doc - it's as if the template was completely ignored. Has anyone else has seen this before? Any ideas re what could be causing it? Cheers, Robin

On other wikis I know there is a way to find how many references there are to a page, and also a way to see a list of all the pages with links that lead to a page (i.e. backlinks). I googled for this for xwiki, and found a couple of posts, but didn't have any luck figuring it out. Does anyone know if there is a way to get xwiki to do this?

RE: [xwiki-users] HQL Queries - multiple objects
by Esbach, Brandon 21 Apr '06

21 Apr '06

Hi Jérémi, Not quite - the problem I'm having seems to stem from getDocument usage to collect objects. I've done a bit of testing I guess to illustrate, here is a snippet of the code I currently use (where the problem seems to be at least): ____________ #set ($sql = ", BaseObject as obj where obj.name=doc.fullName and obj.className='XWiki.SampleBookTest001Class' and obj.name<>'XWiki.SampleBookTest001ClassTemplate' order by obj.name asc") #foreach ($item in $xwiki.searchDocuments($sql)) #set($oDocObject= $xwiki.getDocument($item)) #set($bentryobj = $oDocObject.getObject("XWiki.SampleBookTest001Class")) #set($initialReqDate = $oDocObject.display("dtInitialReq","view", $bentryobj)) <tr title="Initial Request Date: ${initialReqDate}"> <td valign="top" width="30%"> [$oDocObject.display("SampleReference","view", $bentryobj)>$oDocObject.name] </td> <td colspan="2" width="50%"> <table border-left="1" width="98%"> #set($objects= $oDocObject.getObjects("XWiki.SamplePartEntryClass")) #foreach($object in $objects) <tr> <td width="50%">$oDocObject.display("PartNum","rendered",$object)</td> <td width="50%">$oDocObject.display("DeliveryRequest","rendered",$object)</td> </tr> #end </table> </td> <td valign="top" width="20%">$oDocObject.display("MVSEngineer","view", $bentryobj)</td> </tr> #end ____________ What I'm finding is that the $xwiki.getDocument() call is making the time-to-run for these details extremely long (removing the getDocument makes this call exremely fast for 130 documents, whereas normally it takes up to and over two minutes, keeping tomcat at 50% during the collection). You can imagine what happens when more than one person gets a listing (tried convincing powers-that-be about pagination, not an option they're willing to allow for this). My thinking (maybe incorrect) was, remove the getDocument() call and replace with a plain data query, so that I don't need to gather the actual document object - though maybe that's the wrong way round? -----Original Message----- From: jeremi joslin [mailto:[email protected]] Sent: 21 April 2006 02:36 To: xwiki-users(a)objectweb.org Subject: Re: [xwiki-users] HQL Queries - multiple objects Hi, i'm not sure if it's what you want. the code below search every page which contains a class "XWiki.CandidatClass" except the page "XWiki.CandidatClassTemplate" and have a property status=$status. #macro (showCandidat $status) #set ($sql = ", BaseObject as obj, StringProperty as prop where obj.name=doc.fullName and obj.className='XWiki.CandidatClass' and obj.name<>'XWiki.CandidatClassTemplate' and obj.id=prop.id.id and prop.id.name='status' and prop.value='$status' order by prop.value desc") #foreach ($item in $xwiki.searchDocuments($sql)) #set($bentrydoc = $xwiki.getDocument($item)) #set($bentryobj = $bentrydoc.getObject("XWiki.CandidatClass")) 1.1.1 [$bentrydoc.display("name","view", $bentryobj)>$bentrydoc.FullName] #end #end Is it what you mean?

HQL Queries - multiple objects
by Esbach, Brandon 21 Apr '06

21 Apr '06

Hi all, I was wondering, is it possible to use a single query to get document details and specified linked objects using one query (specific fields of those objects would be even better)? For example, A document is created using a class template. Inside the document are used two other classes, which are used multiple times. One of those classes is used for critical information that needs to be shown in the document listing. Currently what I do is to return a query based on the class for documents, then loop through those results for document names. Inside each loop I'm performing a second loop for the class with critical information (shown in the listing). This eventually results in some fairly heavy traffic (as you could imagine), which I'd like to resolve. Not sure if this description is clear enough, but any suggestions or idea's would be welcome!

move search bar
by Niyi Oyelade 19 Apr '06

19 Apr '06

How can I move the search bar on the wiki page to the left hand side of the page? I moved every other thing from the right to the left side of the page but the search bar simply got duplicated, one on the right and the other on the left. How can I get rid of the one on the right side becase it basically serves the same purpose as the other one. -- View this message in context: http://www.nabble.com/move-search-bar-t1475162.html#a3990389 Sent from the XWiki- Users forum at Nabble.com.

html area
by CAROLINA RAMIREZ 18 Apr '06

18 Apr '06

All, I have some problems with html area editor. For example, when I copy a text from a editor like open office to my wiki, something happens becouse I can´t change the letter, or the color. When I create a table I can´t manipulate it, it's hard to enlarge the cells, the columns. If I paste text enlarges a cell more than the others. Thanks in advance

Registration form uses GET method?!
by THOMAS, BRIAN M (SBCSI) 18 Apr '06

18 Apr '06

Is there any good reason that the user registration form XWiki.RegisterNewUser uses GET (putting all form fields, including the password, into the URL's query string)? More to the point, is there any special reason that I can't or shouldn't change it to POST? brain[sic]

Hello, I just updated from JVM 1.5.0_05 Tomcat 5.0.28 xWiki 0.9.543 to JVM 1.5.0_06 Tomcat 5.5.16 xWiki 0.9.840 with MySql *4.0.24 *under Windows XP.

basic xwiki installation and first wiki tutorial??
by Joost Kraaijeveld 13 Apr '06

13 Apr '06

Hi, I have installed XWike correctly on a Debian Sarge host, using JBoss and PostgreSQL and the instructions on www.xwiki.org. Is there anywhere a tutorial available the guides me into creating aA *minimal* filled database without all the example, or even an *empty* database with instructions on how to fill the database so that xwiki can start up? In addition, is there a good tutorial (I am afraid that good is: any tutorial that painstakingly simple and step by step, assuming that *I* have to follow it ;-)) on how to create my first and only xwiki on the installation created above? TIA -- Groeten, Joost Kraaijeveld Askesis B.V. Molukkenstraat 14 6524NB Nijmegen tel: 024-3888063 / 06-51855277 fax: 024-3608416 web: www.askesis.nl

Conditions in which xwiki could 'reset' it's content??
by Tchize 12 Apr '06

12 Apr '06

Hello, we are planning to use xwiki as our enterprise wiki. While in test period, we configured xwiki with a few spaces. Due to lack of time, it was running but not used for a few weeks. During that period, we did several tomcat shutdown/restart, and sometimes we had to kill the jvm (because another webapp was too hungry in terms of memory). Yesterday, to my surprise, i discovered the wiki had lost all it's content (i noticed it because there was no logo anymore and no security config, so it didn't find anymore the attached logo file to the XWikiPreferences page and anonymous had full rights). Going to the database, i saw all documents except the xwiki default ones were removed from table xwikidoc (thought the attachements were still there, but attached to document numbers not existing anymore). So my question is, how can this happens? Is it because the wiki was still configured with the following line commented? #xwiki.store.hibernate.updateschema=0 meaning the xwiki tables are reinitialized at each startup (note i did not notice such behaviour in first days) We can seriously not afford this to happen again in production, so knowledge about this is welcomed! regards, David Delbecq

I haven't checked the cookie content, but as I said I did toss the cookies and clear the cache before retrying it. I even closed all the Firefox tabs that had any pages open from the server and did it again. On the Nth restart of the server after this, the problem cleared, so debugging will have to wait until it resurfaces. Since this was only a development/test/experimental instance, it wasn't crucial, and wouldn't have been until I started tearing my hair out over having to use IE. Thanks again.

If the user is registered on your wiki specifically, you can delete them from the admin page XWiki.XWikiUsers. If they are registered on xwiki.com, maybe an xwiki.com admin (of which a number are active on this mailing list) can help - what's the offending user name?

[xwiki-users] XWiki Firefox extension
by Robin Fernandes 10 Apr '06

10 Apr '06

Hi, I've written a very simple Firefox extension that adds a few links to the context menu when you right click a link to an XWiki page. It just checks to see if the link includes 'xwiki/bin/view', and if so, manipulates the URL depending on the action you want to perform. Nothing special, but it might save a page load or two. http://soal.xwiki.com/xwiki/bin/view/Code/FoXWiki Any ideas for further functionality are welcome. Regards, Robin

Re: [xwiki-users] XWiki Firefox extension

Thanks for the ideas. Adding the same menu for the current page when the context menu does not apply to a link is a particularly good idea, will do that asap. More elaborate interaction with the wiki is also an interesting point, will look into that. The strings are already localized using Firefox's locale system, so adding more languages should be a breeze. Yes it would be very beneficial to get this into source control. Any chance of getting a directory on the XWiki svn repository? :) If not, I'll start applying to sourceforge & co.

does user account validation work?
by petteri.karttunen＠kuopionkonservatorio.fi 09 Apr '06

09 Apr '06

...moved this to the users list Hi! In my xwiki 0.9.840 installation I have set the user validation flag on but newly registered users can still log in without activating their accounts. So to say, if user is marked inactive (checked this in db too) he still can log in. I noticed this in xwiki.com too where I registered and directly logged in without "validating" my registration. Is this the intended behaviour for user account validation and if so, what is it actually for? If this is not a bug, what's the best way - if any - to disable a user account without removing it.

Plugin method call "NoSuchFieldError : actualValueType" exception
by Julien Bourdon 09 Apr '06

09 Apr '06

Hi all! I'm trying to develop a plugin to interact with Jena ( http://jena.sourceforge.net) a semantic web framework. I developed the plugin as I documented it in the plugin development tutorial. I have a hello() method which works perfectly. however when I try to call this method: public List<String> test1(){ Vector<String> uris = new Vector<String>(); OntModel model = ModelFactory.createOntologyModel( OntModelSpec.RDFS_MEM_RDFS_INF, null ); model.read(" http://www.dcs.shef.ac.uk/~zzc05jb/environmentOntology/pollutionInventory.r… "); model.read(" http://www.dcs.shef.ac.uk/~zzc05jb/environmentOntology/instances/disposalRe… "); Iterator iter = model.listIndividuals(); while(iter.hasNext()){ OntResource ontClass = (OntResource)iter.next(); uris.add(ontClass.getURI()); } return uris; } I get this exception: Error number 4001 in 4: Error while parsing velocity page Tests.OntologyPlugin Wrapped Exception: Invocation of method 'test1' in class secoia.plugin.OntologyPluginApi threw exception class java.lang.NoSuchFieldError : actualValueType I can't really make sense of it. This method works if i use it form a classic Java application. I copied all the Jena jar files to the webapps/xwiki/WEB-INF/lib directory. Moreover, I don't know where this actualValueType comes from. Does it come from XWiki? Any clue on this problem?

#include<what?>
by THOMAS, BRIAN M (SBCSI) 09 Apr '06

09 Apr '06

The various kinds of #include directives have always puzzled me, but now I think I may have a serious need to understand them. I have seen that some of them are implemented by methods on $xwiki (includeForm, includeTopic, in two incarnations each - with or without rendering, I assume), but I have no understanding of why they are all different. Add in the parse directives and XWiki methods and I am completely confused. Can anyone give me a synopsis of what these are all about? I understand this much: that Velocity directives are read once at parse time, whereas methods can be invoked multiple times in a loop. The problem I need to solve, however, may be a Velocity problem or a caching problem. A menu is called from the left-side navigation menu XWiki.Menu. I have included it via #includeTopic, and it use #includeMacros to bring in a macro that reads a document with a list of objects describing menu items, with a menu label, an href, and a long description. If the href field is a complete URL, it's output as a plain link; if it's a local Wiki document, it's output with XWiki's bracket syntax and its place is held in the menu as a navigational aid. If it is also in the Web reserved for such documents, it's a submenu, and the menu macro is called again (thanks to the earlier thread, I did use a copy of the argument, which is call-by-reference, and saved headaches). All of this works just fine except the first time it's called after the server starts. Instead of the menu text, all I see is the invocation of the macro. Viewing the menu document directly (as I did when I sought to debug it) fixes the problem for all until the next reboot. So what is this? I read some discussion on the velocity-user mailing list about when and how macro templates are loaded, but didn't understand it well; in addition, there is all this confusion about when to include in what way. brain[sic]

Hi, im looking at the code of Main.WebSearch, in particular the SQL that generate... In several places the basis of the search is a sentence: like '%$text%' How difficult is to add to the form a check control for Matching case, and the build the SQL with something like (here is when i need help) like Upper('%$text%') Or something like that, does anybody do this before? Or i start to broke forms :) I assume, need to look at the JDBC Api to see the way i can express Upper or Lower functions... Any help welcome.

Setting JVM options for Tomcat * Windows running Tomcat 5 and later : Go to the "Apache Tomcat 5.0" folder in the Start Menu. Start the "Configure Tomcat application". Note: the configuration can only be started when Tomcat is not running. Select the "Java VM" tab in the configuration dialog. You will see some pre-defined lines in the "Java Options" test box. Append your Java options at the bottom of the option list. For example, to set server mode and allow 512MB of heap memory, append the following: -server -Xmx400m * Windows running Tomcat 4.1 or earlier : place the Java options into the CATALINA_OPTS environment variable. To do this, run Control Panel / System, select Environment Variables and create the CATALINA_OPTS variable, and set the desired option, for example "-server -Xmx400m". * Linux : place the Java options into the CATALINA_OPTS environment variable. For example: "-server -Xmx400m". THANKS TO MARK :)

[xwiki-users] Password Class & passwords for external webservices
by Robin Fernandes 29 Mar '06

29 Mar '06

Hi, I'd like to allow users to access the a web services from XWiki documents via a plugin. However, the web service requires user-specific passwords. What is the best approach to deal with this? One option is to add "Password Class" fields to the XWikiUsers class, and adapt the user template to allow users to set their password when they edit their page. The field's value is not displayed on the page, but the passwords are stored in the XWiki database in plain text, and the user's page is found if a wide search is ran on a substring of the password. Could also add methods to the plugin that store passwords in the database after encrypting them with some private key; they'd then get decrypted within the plugin code before being sent to the web service. This isn't bad, but maybe you guys have better ideas! :) Regards, Robin

RE: HQL question (wasRE: [xwiki-users] SQL hair-pulling)
by THOMAS, BRIAN M (SBCSI) 28 Mar '06

28 Mar '06

Mark: That seemed, intuitively, to be the way that things were put together, and that's encouraging. However, I'm hoping that your claim that the xwiki objects give most of what I need is true, since that's as deep as I hope to have to get into it. Again, I'm acting as proxy to application developers here, so I need to be sure that this is all as easy as it seems. In particular, the joins are hairy - a necessary consequence of the flexible object structure. And I'm still a bit confused about how to parse the results. A use case is this: I have a document that I threw together quickly and easily that lists projects that I am responsible for. Being driven entirely from the objects on the page, it was easy to share, to the point that nearly everyone else who uses it simply uses #includeForm("Brian.WorkPages") - not a good idea from an organizational point of view, but wholly acceptable in a purely experimental environment. Each object on the page lists the name of the project, the name of the project's plan document, and its current status, due dates, etc. For terseness and convenience, I make the project name the text of a link to the project plan document. As success breeds success, I decided it was a really good way to report status to my boss, so I did two things: added a "journal entry" feature to each of the plan documents, which allowed me to add dated comments on document progress and status changes; and created another data-driven page which copied the data from the original page, followed the links to the plan pages, and displayed the project table again, then the journal entries for each one, with intra-page links from the status field text for convenience. In this way, I didn't need to make out a separate weekly status report for my boss; this page would show status at a glance, with links to more detailed information right at hand. This was good, but two things were wrong: first, the projects were listed in the default order in which getObjects() listed them, which was the order of their creation; second, all the journal entries showed up. I wanted the projects to be listed in order by priority and/or due date, and to list journal entries from only the current week. I had already seen that I could modify the WHERE clause in searchDocuments(), and used that to add options to Main.AllDocs to order by date or creator. but getObjects() gave me no such ability, so I had to use search(). And rather than futz around with trying to get the search results to fit the same wiki Object format, I followed another example and called getObject() with the objects' number fields, which was all I returned from the query. I could also have used getObjects with a list of objects, but I didn't think of it, and am still not sure I'd know the right way to turn the returned ArrayList into a Vector. In short, the SQL wasn't hard; tying all the attributes to the BaseObject wasn't hard, when I wanted to do it, but for one thing, when I returned a BaseObject only, I wasn't able to find any of its properties attached to it at all, and none of the syntax that I expected to be able to use to request all fields worked - I suspect because the query schema is virtual and each field had to be specified. In other words, "select obj.* from BaseObject as obj, ..." was refused. The other matter I asked about before was why I couldn't return an arbitrary expression as I could with SQL, even though the same expression had worked in a qualifier on the same query. I really wanted to ditch all the code I had written to figure out when one week ago was, and since it was already in my qualifier, I thought I'd return it also, but Hibernate didn't like that. brain[sic] -----Original Message----- From: Mark Robinson [mailto:[email protected]] Sent: Friday, March 24, 2006 11:14 PM To: xwiki-users(a)objectweb.org Subject: Re: HQL question (wasRE: [xwiki-users] SQL hair-pulling) Hi Brian. Sorry for the lack of clarity there, it was late in my part of the world. This is my understanding of it in general, but I am sure someone can correct how it relates to xwiki along the way. Hibernate hides the process of creating objects and populating them with data retrieved from the database. The Java objects have an almost direct relationship to the database structure. The tables are represented by classes and the columns are represented by properties of the object. So when an object is created, it already fully represents the table structure. This gives you the advantage of being able to describe the equivalent of SQL queries very simply by referring to their properties. There are getters and setter for the properties so to select a particular item from the database all you have to do is "get" that property with the value you want. Example: Instead of "SELECT * FROM foo WHERE id = '22'" you could just use something like ... item = getSession().get(foo.id, '22'); This is the beautiful bit about it. "item" is now an object with all the data from that row of the table and you can adjust the properties with the setter methods. Example: Instead of "UPDATE foo SET Name='New Name', Age='36' WHERE id='22'" item.setName("New Name"); item.setAge("36"); getSession().update(item); Note: When you want to update the database you just call method (eg update(item)) and your object returns all the current object properties to the appropriate row in the database. So how does this relate to XWiki? The mapping of xwiki object to the MySQL database is in xwiki.hbm.xml. Using the hibernate query from the category field in the blog as an example. Example: select prop.value from BaseObject as obj, StringProperty as prop where obj.className='Blog.Categories' and prop.id.id = obj.id and prop.id.name='name' >From looking at the mapping I can see that "BaseObject" is of the class "com.xpn.xwiki.objects.BaseObject" and it is mapped to the table "xwikiobjects" in the database. It is then aliased to "obj". I can also see that the property "className" of "obj" is mapped to "XWO_CLASSNAME", "name" is mapped to "XWO_NAME" and "id" is mapped to "XWO_ID". "StringProperty" is a joined subclass (hibernate returns all the subclasses automatically) and is mapped to "com.xpn.xwiki.objects.StringProperty" which relates to the table "xwikistrings". In that subclass "value" is mapped to "XWS_VALUE". StringProperty is then aliased as prop. So after all that, what we are trying to say is something to the effect of "give me a list object that is made up of the names of the categories". Why do we have to do it like that? Because the data is described generically in the database schema and stored in 3 different places. To retrieve it you need to ask first to find the objects of the wiki defined class 'Blog.Categories' then you need to retrieve the properties related to those objects (in this case, only the strings) and then you want to list the values of those strings. So the strength of XWiki is that you can create classes, instances of those classes and manipulate them through the wiki pages to represent almost anything. It also means that it is very independent of the backend (as shown by using HQSQL in the standalone version). However, the drawback is that you need to understand clearly how your classes are put together because the data is spread across the database (Remember, your classes/objects that you have created are represented in the database by the generic BaseObject and its properties). Getting back to using this info. I find mostly that the $xwiki, $request and $doc objects give you access via the api to most of what you need anyway without getting that deep into it. Example: From the mapping file I can see that the string property "fullName" in class com.xpn.xwiki.doc.XWikiDocument (eg $doc or doc) relates to "XWD_FULLNAME" in the "xwikidoc" table. So if I wanted to list all the different webspaces in my xwiki with the default page of "WebHome" I know that "doc" represents the "xwikidoc" table and "fullName" represents "XWD_FULLNAME" so I write the "where" part of the query as "doc.fullName like '%.WebHome'" The searchDocuments method of $xwiki translates this as "select distinct doc.web, doc.name from com.xpn.xwiki.doc.XWikiDocument as doc where fullName like '%.WebHome'" So you end up with a list as demonstrated below in a Velocity setting. #set($whereclause = "doc.fullName like '%.WebHome'") #set($mylist = $xwiki.searchDocuments($whereclause)) 1.1 The list returned \\$mylist 1.1 Individual items #foreach ($item in $mylist) #set($thisdoc = $xwiki.getDocument($item)) * $thisdoc.getFullName() #end Hope that wasn't too wandering and full of mistakes. It is just from poking around a bit inside so could be completely misguided. I look forward to comments. Cheers, Mark On 25 Mar 2006, at 2:30 AM, THOMAS, BRIAN M ((SBCSI)) wrote: Okay; will do.

Comment Spam

Hello All, My xWiki is beginning to get a lot of comment spamming; is there a way to force a user to enter some random value displayed in an image, or to send me an e-mail, etc? I would prefer the site to send me an e-mail anytime a new comment is added anywhere; at least this would be a good start. Anyone have any ideas?

Graphviz plugin
by Mark Robinson 25 Mar '06

25 Mar '06

Hi All. Has anyone played with accessing the graphviz plugin from Velocity? I have managed to get it creating graphs from my objects and displaying with various options, but I seem to be stumbling on the last step of adding client side image maps to allow the user to drill down easily. The problem is that if I call $xwiki.graphviz.outputDotImage($graph, "cmapx", true) it will only render the mapping file (which I need) instead of the whole page so I am assuming I have to call $xwiki.graphviz.getDotImage($graph, "cmapx", true) and then display it. I have also tried to write it, then access it via $xwiki.getExternalURL() but no go. It works as expected when you retrieve it from a separate file, but not on the fly. Just a reference returned that doesn't seem to respond to Name or Value methods. Example below: #set($graph = 'digraph abstract {"Node 1"[URL=WebHome];"Node 2"[URL=WebHome]; "Node 1" -> "Node 2";}') #set($graphfilename = $xwiki.graphviz.writeDotImage($graph, "jpg", true)) <img src="/xwiki/bin/dot/$doc.web/$doc.name/$graphfilename" usemap="#abstract"> #set($graphmap = $xwiki.graphviz.getDotImage($graph, "cmapx", true)) $graphmap Any suggestions are gratefully accepted. Cheers, Mark

XWiki's feed plugin can't parse XWiki's RDF
by Robin Fernandes 25 Mar '06

25 Mar '06

As demonstrated by this page http://www.xwiki.org/xwiki/bin/view/Sandbox/includeOwnRSS the XWiki feed parser plugin appears to fall over when parsing a feed generated by XWiki. Other parsers have no problems. The the stack trace isn't reported with the error so it's a bit hard to see exactly what's going wrong... though I guess it's failing in FeedPlugin.getFeedForce(..). I thought it might be a formatting problem in the rdf template, exposing some fragility in the parser... However, invoking rome as follows (using rome 0.7) works fine: public class Feedread { public static void main(String[] args) throws IllegalArgumentException, IOException, FeedException, FetcherException { // FeedFetcher feedFetcher = new HttpURLFeedFetcher(); URL feedURL = new URL("http://www.xwiki.org/xwiki/bin/view/Main/WebRss?xpage=rdf"); SyndFeed feed = feedFetcher.retrieveFeed(feedURL); feedFetcher.setUserAgent("XWikiBot"); System.out.println(feed); } } So I'm not sure what's breaking when this happens inside XWiki. The reason want to do this is that on my xwiki homepage I'd like to include a bunch of feeds, some external, some from the wiki itself. It would make my life easier if I could use my same macro to display them all, rather than using the feed plug for the external ones, and direct hql queries for the local ones. Regards, Robin

RSS feed/cache question
by KIDWELL, REX (SBCSI) 24 Mar '06

24 Mar '06

Can someone provide information on how RSS feeds and the Xwiki cache system work together? What's known so far. 1) The xwiki/WEB-INF/xwiki.cfg file contains the following lines xwiki.store.cache=1 xwiki.store.cache.capacity=100 2) Based on the build.xml file included in the source, xwiki is configured to use ehcache-1.1, oscache-2.0.2, and swarmcache. 3) grep results on source files indicate that OSCache is being used by Xwiki. Questions 4) Does item 1) mean caching is enabled for RSS feeds? 5) Does "xwiki.store.cache.capacity=100" relate to OSCache's "cache.capacity" configuration property? Are they the same? See the following URL http://wiki.opensymphony.com/display/CACHE/Configuration 6) Please confirm that OSCache is being used by Xwiki 0.9.840 for RSS feeds That's enough, for now and thanks for any help you can provide.

[xwiki-users] Plain text "select x into y" in any document breaks xwiki.com
by Robin Fernandes 24 Mar '06

24 Mar '06

Hi, Trying to view/preview any page on free xwiki.com hosted containing the text: select x into y causes nothing more than the following message to be displayed: We are currently doing performance maintenance of our servers. The service will be back in a few minutes. Sorry for the inconvenience. 'x' and 'y' can be any number of words. Note that this happens with plain text - no velocity or anything, e.g. simply a document containing the text: Press the 'add' button to select which plugin is loaded into the current effect slot. I haven't raised this as bug on JIRA since I can't reproduce it outside of xwiki.com hosted wikis. So I guess it's some configuration issue or some extra protection gone wrong on xwiki.com. Thanks, Robin.

LDAP Integration

Hi, just testing the LDAP integration on a development build (head). I do manage to authenticate against my LDAP server and I'm logged in afterwards, but the username is not displayed (only: $docuser.display("first_name", "view", $objuser)) and somehow I'm not really "logged in". I don't have the permissions I normally have, when I'm a logged in user. Do I have to do anything extra for the LDAP integration? Do I have to create each user which exists in ldap also in the xwiki db? (this apparently works..)

Jérémi: Aha! I should have read my mail before sending my last note, which I began composing last night. That clears a lot of the mystery. I will save my other questions until after I've read your reference; thank you. But it re-raises for me the issue I had thought resolved - that of where the boundary of queryability may be. I had assumed that it was the same as the boundary of the XWiki-defined object model, as it would seem logically if it had to be supported as a database map, but since it's a general-purpose persistence tool, might that assumption be wrong? Probably, any queryable object would have to be modeled in the database, but it's a grey area in my understanding. I do note that date fields are returned as java.sql.Timestamp rather than as java.util.Date, in case that has any bearing on the matter. brain[sic] -----Original Message----- From: jeremi joslin [mailto:[email protected]] Sent: Thursday, March 23, 2006 10:47 PM To: xwiki-users(a)objectweb.org Subject: Re: [xwiki-users] SQL hair-pulling On 3/24/06, THOMAS, BRIAN M (SBCSI) <bt0008(a)att.com> wrote: > As mentioned in an earlier message, I got into the $xwiki.search() > world yesterday, and am thoroughly confused. > > The main problem seems to be that the XWiki database schema and the > schema used in all of the $xwiki.search() queries I have found are > completely disjoint. > > Instead of the documented tables and columns, what seems to be used is > a schema which reflects the object model within XWiki.

SQL hair-pulling
by THOMAS, BRIAN M (SBCSI) 24 Mar '06

24 Mar '06

As mentioned in an earlier message, I got into the $xwiki.search() world yesterday, and am thoroughly confused. The main problem seems to be that the XWiki database schema and the schema used in all of the $xwiki.search() queries I have found are completely disjoint. Instead of the documented tables and columns, what seems to be used is a schema which reflects the object model within XWiki. This would really be convenient if true; is it? brain[sic]

Backport of Import Export Script
by Mark Robinson 23 Mar '06

23 Mar '06

Hi All. This is probably most appropriate to Jeremi, but I would appreciate anyones thoughts on the subject. XWiki is a phenomenal piece of software that I am thinking of new uses every day. I am currently running 0.9.840 on one of my servers and am a little bit paranoid about upgrading until later in the year, as our application is growing at a furious rate and I would like it to stabilise a little before we go through an upgrade. However, some of the new features are very tempting (I am using the standalone for testing). Ideally I would like to use your XWiki/ImportExport script to create user configurable exports on the existing data and was wondering how involved the underlying adjustments would be to the code to make it work with the stable version. The script looks for $export. Is this a java class that is put into a xwiki context in the later release? If so, is it self sufficient enough to compile and add to an existing installation, or is it too dependent on other code in the later version? With custom java classes, is there a straight forward description somewhere on putting them in an XWiki context so they can be used by Velocity? In a mildly related point: I have deployed DWR (https:// dwr.dev.java.net/) side by xwiki in another testing installation for some AJAX experimentation and it seems to be co-habiting without too much trouble. Apologies for the basic questions, but I am currently on a steep learning curve with this and appreciate any help offerred. Have a great day. Mark.

by Gaël Blondelle - EBM WebSourcing 23 Mar '06

23 Mar '06

Hi all, I try to print future events in the left menus, but it looks that the test of the event start date is always evaluated to false. #foreach($event in $xwiki.getDocument("Main.EventCalendar").getObjects("XWiki.CalendarEvent")) #if ($event.getStartDate().getTime().after($xwiki.getDate())) $event.startDate $event.endDate $event.description #end #end Any idea or suggestion? Regards, Gaël Blondelle EBM WebSourcing

RE: [xwiki-users] Date value compare (and update on date arithmetic)
by THOMAS, BRIAN M (SBCSI) 23 Mar '06

Jérémi: You make it look easy, but it took me a good long bit of searching and trial-and-error investigation to figure out how to get a real Date object out of an XWiki object field. And you perform a little leger-de-main which I have not found explained anywhere: the expression $obj.XWikiObject.date.value is equivalent to $obj.XWikiObject.getDateValue("date"). Unfortunately, this is not suitable for use as an lvalue, but it makes a nice shorthand. Is this documented anywhere (other than in the source)? I noted the same thing when I found, in some sample code, a call to a (seemingly) nonexistent method $xwiki.getCalendar(). Happily, simply writing $xwiki.calendar in a document yielded an object identifier containing the classname com.xpn.xwiki.plugin.calendar.CalendarAPI, so it seems that XWiki was fiddling my call into $xwiki.get("calendar"), which is documented to return a plugin API, which before this had meant nothing to me (either that, or the plugin augmented com.xpn.xwiki.api.XWiki with a getCalendar() method, which is what I thought before I saw the above). Velocity, of course, turns any rvalue reference to $obj.foo into a call to $obj.getFoo() or $obj.getfoo(), and likewise any lvalue reference in a #set into a call to $obj.set[Ff]oo() with the RHS as its argument. But this trick is different, because at least in the first case it has to know the navigation of a particular XWiki-specific class hierarchy. Nice shorthand; would be nicer if it were explained somewhere... Okay, I'll do it... By the way, that $xwiki.calendar property finally got me to an answer to my date arithmetic problem, thanks to Java reflection. The task was in a project status reporting page, where I wanted to ignore records more than a week old. The problem was that I could find no way at all to do date arithmetic in a Velocity script, because the time value returned from java.util.Date.getTime() is a long integer, which (until the next release of Velocity, at least) can't be used in an arithmetic expression. I could have used the Date functions to format a date, manipulate the string version, and then parse it, but that would be far too difficult, inflexible, and error-prone even ignoring the fact that those methods were deprecated. It works like this, for those who are interested: First, $xwiki.calendar has a method getCalendar() which, in the version without arguments, returns a java.util.Calendar initialized with the current date. Because it inherits from java.lang.Object, it is Cloneable, so I clone()d it to get a copy that I could set back seven days, without disturbing the original object (I learned this the hard way: the returned object was a reference, and changes via the copied reference changed the original). Turning back the clock in a java.util.Calendar by seven days is quite simple in Java - formally speaking, it's java.util.Calendar.add(java.util.Calendar.DAY_OF_YEAR, -7). However, this isn't Java exactly; we can call the add() method easily enough, because we have a Calendar object, but that DAY_OF_YEAR symbolic constant isn't accessible that way, because apparently Velocity doesn't translate field references, only method calls. The final expression was $xwiki.calendar.calendar.class.getField("DAY_OF_YEAR").int #set($wcal = $xwiki.calendar.calendar.clone()) ## copy of java.util.Calendar with current time $wcal.add($wcal.class.getField("DAY_OF_YEAR").int, -7) ## set the calendar back one week. #set($weekago = $wcal.time) ## get the resulting date as a java.util.Date object After this, when I wanted to see whether date "donedate" from an object was more than a week old, I wrote something like this: #set($weekold = $obj.xWikiObject.donedate.value.before($weekago)) which worked just fine. Of course, since I also wanted to sort those records on other than the default field, I needed to do an $xwiki.search() call with a custom query, and SQL can easily do date arithmetic. That brings up another topic, because I was foolish enough to try it... brain[sic] -----Original Message----- From: jeremi joslin [mailto:[email protected]] Sent: Wednesday, March 22, 2006 8:25 AM To: xwiki-users(a)objectweb.org Subject: Re: [xwiki-users] Date value compare On 3/22/06, jjanssen(a)nl.swets.com <jjanssen(a)nl.swets.com> wrote: > Hello, > > I've got several classes in which I use date attributes.

Hello, I've got several classes in which I use date attributes. Is there a way to list objects of such a class, but only those in which the value of the date attribute is before current date? Thanks again, Joep Janssen

problem with skin for a space
by Lars Schmidt-Thieme 20 Mar '06

20 Mar '06

Dear xwiki developers, first of all, thanks for XWiki, which is really an awesome tool and one of the most advanced Wikis I know of. I have a problem attaching a skin to a space via the webpreferences of the space. What I did: 1. I created an empty page XWiki.WebpageSkin and attached a new objekt also called "XWiki.WebpageSkin" of class XWiki.XWikiSkins. I removed all contents from the "style" box and entered "THIS IS THE HEADER" into the header box, just to see, if the skin is used or not. 2. I testet the skin by appending ?skin=XWiki.WebpageSkin and to a page and this worked fine. 3. I edited the Main webpreferences (via More Actions/Space Preferences on Main.WebHome) and entered "XWiki.WebpageSkin" in the "skin" box. But this did not take effect. When I did the same for the XWiki preferences (instead of the space preferences), it did work properly, but for all spaces, of course. What did I do wrong? How can I configure different skins for different spaces? Any help would be highly appreciated & thanks a lot in advance & best Lars

Hi folks, I try to display RSS coming from Google about ObjectWeb on my nice XWiki wiki. The URL is : http://news.google.com/news?q=objectweb&output=RSS&ned=us&lang=en So I've added in my XWiki: {rss:feed=http://news.google.com/news?q=objectweb&output=RSS&ned=us&lang=en} unfortunately I obtain the following errounous message : rss: Error processing http://news.google.com/news?q=objectweb&output=RSS&ned=us〈=en: Server returned HTTP response code: 403 for URL: http://news.google.com/news?q=objectweb&output=RSS&ned=us〈=en it seems the parameters are bringing issues. I've tried to escape the = character with '\' but it didn't work. Does anyone know how can I do that ? Thanks -- Xavier MOGHRABI - Consortium ObjectWeb

Is it possible to put an attached file at one page, and from another page link to that file? Example, we attach the file File.xml to the page Main.Files And then on the page Main.List we want to include a link to the File.xml file?
