[xwiki-users] Statistic activation problem
by GeLo 03 Nov '09

03 Nov '09

Hello, I had activated the statistics in xwiki.cfg : xwiki.stats=1 xwiki.stats.default=1 But in the Stats space, no statistics are registered. In the config file, we can read : "storage can be enabled/disabled by wiki using the XWikiPreference property "statistics". What does it mean ? I don't have any "statistics" attribute in the XWikiPreferences object. XWiki initially installed in 1.9.2 and upgraded to 2.0.2. Thank you for your help. Maxime

Re: [xwiki-users] XWiki RESTful API issue on localhost
by Dilipkumar Jadhav 03 Nov '09

03 Nov '09

Finally, I have a working version of the code to access the Xwiki RESTful API. It worked smooth on a Tomcat 6.0.14 + JDK 1.5 machine. But had to make certain changes to the bootstrap files for JDK 1.6 as I mentioned in the previous post. I have used the Apache HTTP HTTPClient 3.1 jar files here but soon will upgrade that to Apache HTTPClient 4.0. The only change in the code from the one posted at http://platform.xwiki.org/xwiki/bin/view/Features/XWikiRESTfulAPI are the lines Unmarshaller un = context.createUnmarshaller(); and the line Page page = (Page) ((JAXBElement) un.unmarshal(getMethod.getResponseBodyAsStream())).getValue(); The default object that getMethod returns turned out to be a JAXBElement rather than a Page object. Hence, had to do some class casting. A big thanks to Fabio Mancinelli & Sergiu Dumitriu for helping me out on this one. Just one more request though. Do we cast the getMethod.getResponseBodyAsStream() to Tags class (if we want to retrieve a list of pages based on their tags) or the SearchResults class (if we want to retrieve pages returned through a page search). Even though, I cast the getMethod.getResponseBodyAsStream to the tags class, my compiler still throws an error for class cast exception : org.xwiki.Pages. Could someone please post a snippet to access pages with specific tags or any other complex querying using classes in the org.xwiki classes. Any help on this would be greatly appreciated friends. /* JDK: 1.5 Tomcat: 6.0.14 (Xwiki server) Libraries: Apache HTTPClient 3.1, JAXB 2.1, Apache Commons Logging 1.1.1 & Apache Commons Codec 1.4 Class File Dependencies: org.xwiki package of class files generated from the XSD file at http://svn.xwiki.org/svnroot/xwiki/platform/core/trunk/xwiki-rest/src/main/r esources/xwiki.rest.model.xsd with the help of the XJC compiler available in the JAXB 2.1 distribution */ import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.util.List; import javax.xml.bind.JAXBContext; import javax.xml.bind.JAXBElement; import javax.xml.bind.JAXBException; import javax.xml.bind.Unmarshaller; import org.apache.commons.httpclient.HttpClient; import org.apache.commons.httpclient.HttpException; import org.apache.commons.httpclient.methods.GetMethod; import org.xwiki.Page; public class Main { public static void main(String[] args) throws JAXBException, HttpException, IOException { HttpClient httpClient = new HttpClient(); JAXBContext context = JAXBContext.newInstance("org.xwiki"); Unmarshaller un = context.createUnmarshaller(); GetMethod getMethod = new GetMethod("http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/We bHome"); getMethod.addRequestHeader("Accept", "application/xml"); httpClient.executeMethod(getMethod); Page page = (Page) ((JAXBElement) un.unmarshal(getMethod.getResponseBodyAsStream())).getValue(); System.out.println(page.getCreator()); System.out.println(page.getCreated()); System.out.println(page.getFullName()); System.out.println(page.getXwikiAbsoluteUrl()); } }

[xwiki-users] Is there a simpler way to upgrade between versions?
by Nigel Smith 02 Nov '09

02 Nov '09

Hello, I'm a very keen and happy user of xwiki. We use it for our corporate intranet and our users love it! I generally move directly between major versions as soon as convenient. The factor that has the most bearing on when we upgrade is the ease with which we can move between new versions. I remember seeing an items relating to simpler installation. I'd like to ask when that is scheduled to be worked on, and perhaps share some of my experiences in upgrading and some suggestions. I'd like to give you an idea of what has to be done to move between versions. It's a bit long, so bear with me, but here it is: * Download the latest xwiki xar to your local machine * Download the latest xwiki war to the machine which will run xwiki. * Backup the entire xwiki installation directory (the one that contains the directories database, jetty, lucene etc), and move the old directory aside (rename to xwiki.old) * //We do this to easily be able to get the jetty, hsql, etc dirs back in place//: Restore the backed up xwiki directory, thus putting the xwiki dir back in place * Delete the directory xwiki/webapps/xwiki * In xwiki/webapps, create an xwiki directory * Unzip the xwiki war in the xwiki/webapps/xwiki directory * //Getting our corp logo back//: Copy xwiki.old/webapps/xwiki/skins/toucan/mywiki.jpg to xwiki/webapps/xwiki/skins/toucan/mywiki.jpg * //Next few steps: need to merge old config with new config//: Do a diff between xwiki.old/webapps/xwiki/WEB-INF/xwiki.cfg and xwiki/webapps/xwiki/WEB-INF/xwiki.cfg. Update xwiki/webapps/xwiki/WEB-INF/xwiki.cfg as needed. * Do a diff between xwiki.old/webapps/xwiki/WEB-INF/xwiki.properties and xwiki/webapps/xwiki/WEB-INF/xwiki.properties. Update xwiki/webapps/xwiki/WEB-INF/xwiki.properties as needed. * Do a diff between xwiki.old/webapps/xwiki/WEB-INF/hibernate.cfg.xml and xwiki/webapps/xwiki/WEB-INF/hibernate.cfg.xml. Update xwiki/webapps/xwiki/WEB-INF/hibernate.cfg.xml as needed. * //This is the part we fear the most, for we might accidentally delete some configuration that we need and we would need to start the whole process again//: Start XWiki and import the default wiki xar. Be careful of what you import - read the instructions at http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HUpgrading… . ** The normally excluded pages from import are: *** XWiki.XWikiPreferences *** XWiki.XWikiGroups *** XWiki.XWikiAdminGroup *** XWiki.WebPreferences *** XWiki.WebHome *** XWiki.XWikiUsers *** XWiki.XWikiAllGroup *** XWiki.DefaultSkin *** Main.WebHome *** Panels.QuickLinks *** Panels.Search * //We customise the PDF cover//: The PDF covers files has been manually modified. Do a diff between xwiki.old/webapps/xwiki/templates/pdfcover.vm and xwiki/webapps/xwiki/templates/pdfcover.vm. Merge the differences. * //We customise the PDF footer//: The PDF footers file has been modified by hand. Do a diff between xwiki.old/webapps/xwiki/templates/pdffooter.vm and xwiki/webapps/xwiki/templates/pdffooter.vm. Merge the differences. * //We do this to be able to specify the PDF template to use in "Export as PDF"//: The Menuitems have to be edited by hand, so that PDFs are exported using the correct stylesheet. Do a diff between xwiki.old/webapps/xwiki/templates/menuview.vm and xwiki/webapps/xwiki/templates/menuview.vm. Merge the differences (there should only be one line).As you can see, there are quite a few steps, and it normally takes 1/2hr - 1hr to complete. Note that we will move to MySQL eventually, but the performance of HSQL is OK ATM. This may not be the most optimal upgrade path, so if there are any clear improvements you can see, please let me know. The part that needs to be improved upon the most, in my opinion, is the "import default XAR" step because it is easy to overwrite an important page. I would like to put in a big vote for separating information that can be modified by the user from information that xwiki needs to be able to operate, that comes with default xwiki. Perhaps making certain pages "system" pages so that it is clear that if a page is modified it may interrupt the operation of the wiki, and may be difficult to upgrade. The next most important thing to be improved is the storage of configuration that now sits in xwiki.cfg and xwiki.properties. This is difficult to migrate between versions. If this was automatically migrated between versions like the pages are, this would be much easier to manage. At our office we have a large system written in Java and we solved a similar problem using the Java Preferences API. Being able to fully customise the PDF layout (not just the stylesheet) inside xwiki, and also specify a default PDF style sheet to use during export would be #3 on my list. I'm interested in hearing some thoughts. Regards, Nigel

[xwiki-users] Grid/LiveTable edit restrictions
by Radek Rekas 02 Nov '09

02 Nov '09

Hi, I'd like to use the Grid/LiveTable components to list data and create links to edit pages for that data. I would also like to add restrictions so that only users who created that data can edit it. >From my understanding it is not possible to restrict edits for individual xwiki class objects to only users who created that object (along with an administrator user) as edit permissions can only be set at the page level and not at the individual object level. The solution I was thinking about was to create a new page for each record then restrict edit permissions at the page level. This would however require me to aggregate all of the xwiki class objects on a single page so that they could be used with the grid/LiveTable component. I can't however see a way of doing this. Is this possible or is there a better way of doing this? Thanks in advance, Radek

Hi Sergiu, I happen to use Tomcat 6.0.18 as the servlet container and JDK 1.6. But I also chanced upon this article while digging for more info: http://blog.spaceprogram.com/2007/05/how-to-fix-linkageerror-when-using-jaxb .html http://java.sun.com/j2se/1.5.0/docs/guide/standards/ I am trying to fix this using the endorsed library mechanism. It seems only JDK 1.6 would have the java.lang.LinkageError and not JDK 1.5. Will keep you posted once this is done. Thanks Sergiu...

[xwiki-users] Replicated JBossCache
by Andy Dale 02 Nov '09

02 Nov '09

Hi, I am currently trying to set up XWiki Enterprise 1.6.1 to use JBossCache in REPL_ASYNC mode, but I am current experiencing a few issues. I discovered that the directory structure WEB-INF/cache/jbosscache is not correct, so I renamed the folder jbosscache to jboss. The default.xml file had an incorrect tag EvictionConfig instead of the correct EvictionPolicyConfig. After fixing the 2 minor issues (tested in LOCAL mode) mentioned above, nothing can be stored in the cache due to serializable issue, the stack traces: With UseLazyDeserialization = true 2009-07-13 12:30:05,080 ERROR [STDERR] org.jboss.cache.CacheException: java.io.NotSerializableException: Marshalled values can only wrap Objects that are serializable!

Hi Sergiu, Thanks for taking the time out to look into the issue. I reinstalled the XWiki instance & now have a clean XWiki instance. I checked the xwiki/WEB-INF/lib folder and I see that the JAXB library shipped with XWiki is JAXB2.1 (jaxb-api-2.1, jaxb-fluent-api-2.1.8, jaxb-impl-2.1.10,jaxb-xjc-2.1.8,jaxrpc-api-1.1 & activation-1.1). Tried accessing the URL http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome directly from the browser. Following is the java.lang.Linkage error that I get: java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/C:/Tomcat6.0/webapps/xwiki/WEB-INF/lib/jaxb-impl-2.1.10.jar!/com/s un/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API.

[xwiki-users] XWiki RESTful API issue on localhost
by Dilipkumar Jadhav 01 Nov '09

01 Nov '09

Hello folks, The REST example at http://platform.xwiki.org/xwiki/bin/view/Features/XWikiRESTfulAPI seems to be working fine to quite some extent. I retrieved the xwiki.org Main.WebHome page in the XML format. However, the same code returns empty result if I look for the Main.WebHome on localhost:8080/xwiki. Is there something that I need to enable on my localhost XWiki instance. I see that xwiki.org has been upgraded to version 2.0.2 which is the same version on my machine. I am using tomcat 6.0.18 with MySql 5. Also, the URL http://www.xwiki.org/xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome returns a well formed XML document. However, the URL http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome returns an error : XML Parsing Error: no element foundLocation: http://localhost:8080/xwiki/rest/wikis/xwiki/spaces/Main/pages/WebHome Line Number 1, Column 1: in Mozilla FF & the error : XML document must have a top level element.
