Re: [xwiki-dev] xwiki installation not too friendly

Or you include ant.jar in your distro and use your own wrapper scripts to call it. In the end, though, the best reason I've found to do as much as possible in Ant and write only the simplest wrapper scripts is that means you keep your code and build/deploy process as platform independent as possible which makes debugging a lot easier. You're right about importing default data. I can't really see any clever way to do this that is database agnostic. One idea is that you write a simple Main class that uses hibernate and your persistent classes to programmatically create the data. This in theory would then work for any database as well and could even be the start of unit testing with your persistent classes... My main point here though is I agree you don't want to force users to become developers, but it's even worse that users have to become DBA's. In my country a database admin usually gets paid more than a developer and requires more specialized skills ;-) Cheers, Jason > If you want to help you are welcome to. > > Ludovic > > Jason Novotny wrote: > >> >> Hi Ludovic, >> >> I've been looking at the instructions at >> http://www.xwiki.org/xwiki/bin/view/Main/InstallLinuxTomcat and there >> are about 8 steps too many for this software to gain widespread >> adoption in my opinion.

xwiki installation not too friendly

by Jason Novotny

Hi Ludovic, I've been looking at the instructions at http://www.xwiki.org/xwiki/bin/view/Main/InstallLinuxTomcat and there are about 8 steps too many for this software to gain widespread adoption in my opinion. One of the biggest issues I see is that it uses Hibernate which is great since technically db tables can be auto generated using the Hibernate schemaexport tool with the xwiki mapping file to create tables in any database of your choosing. However, it looks like I specifically need MySQL and I don't know why. I look at the JBoss + Postgres install page and sure enough it points out the flaws of this approach: "Download the sample database and convert for Postgres. See PostgresDatabase <http://www.xwiki.org/xwiki/bin/view/Dev/PostgresDatabase> -> This tool has been made by Nicholas Vesser.. It was done with an old mysql database for XWiki.. You should try it with the latest database.." hmm, not fun. Personally, what I would like to see is this: 1) Download xwiki.zip 2) Run "ant install" which performs: Creating/deploying xwiki webapp to your Tomcat that you set in your build.properties Uses schemaexport to generate tables in your database that is defined in the hibernate properties file 3) Start your server and voila! Further, it could use hsqldb as a default so if you didn't reconfigure the hibernate properties file it would simply use hsqldb which can be bundled with the wiki webapp and used for test purposes. How does this sound? Cheers, Jason

Groups external to xwiki

by lauzon＠us.ibm.com

Hi all. I have a need to determine group membership based on criteria defined outside xwiki, and wondering if anyone has done this, or can at least suggest a direction. We have criteria for groups defined in LDAP, such things as your department or things like that. I would like to be able to say that for a specific space, only people in so-and-so department are allowed in. However department should be only one criteria; in general I want to use an LDAP search the queries on an arbitrary set of attributes. In addition we have something called "Bluegroups", in which you can define a group name and then specify the members through either picking members individually, or again through an LDAP search. To do this, my idea was that the user would manually create an XWiki group, and then as a member give something like "ldap:(dept=HTV)", or maybe "bluegroups:Support team". Even better would be the ability to put a value such as this in the Access Rights, under group, but I don't think things are setup that way. Anyway, looking at the API, it seems like I need to implement listGroupsForUser(), which is difficult because the group members are not stored in the db. I'm left with querying all the members which begin with "ldap:" or "bluegroups:", determing which the user is a member of via an LDAP call, and then returning them. I could cache these, but since I'm not going to get notifications of group membership changes, I would need to invalidate the cache once a day or something like that. Does this seem like the most reasonable way of doing things? Or is there something that would make my life really easy and wonderful? Thanks in advance ... shawn.

Table 'xwiki.xwikilock' doesn't exist

by Miguel Angel Bayona Pérez

Hi, i've just installed xwiki (with the sample db: first with xwiki-db-0.7.460.txt and then with xwiki-db-0.9.1.sql) and when I edit (as admin) a page and save it I get the error message (see below). The page is correctly saved though. I have looked in the Db and the table "xwikilock" does no exist. The following is the list of the tables (see below) in the xwiki DB. I'm using java 1.5, tomcat5.5, mysql4.1 Dou you know what the reason for the problems can be? Thanks in advance, Miguel A.

Re: Off-Setting Infobox

by Ludovic Dubost

Hi, you can use HTML in XWiki pages so using styles with "width, float and clear" allows to do this. Now a nice macro would be great, so I tried to do a set of macros that simplifies creating an InfoBox. Check it out at: http://www.xwiki.org/xwiki/bin/view/Dev/InfoBox Ludovic BKY wrote: > Hi, > > I read all the help on Xwiki I could find, but I didn't see anything > about how to put a table on the site of text for an infobox, like on > Wikipedia (like: http://en.wikipedia.org/wiki/United_States , I want > the info box (table) on the side of text so it does not take up all > the page) > > If it's done with a table, I don't know how to do it.

how to sort objects?

by lauzon＠us.ibm.com

I have a page with a number of objects, which I want to display in sorted order. I currently have code which can view all the items (the page as well as the class is "Main.Teams": #set($teamsdoc = $xwiki.getDocument("Main.Teams")) #foreach($team in $teamsdoc.getObjects("Main.Teams")) * $team.get('name') #end I allow users to add new teams, but they always go to the bottom of the list. However I'd like to print out them in order by the "name" property. I've tried using groovy for this, but I just can't get simple things (like printing list contents any way other than "print teams") to work. Can anyone help? Thanks ... shawn.

by Duke Tantiprasut

Hi All, Is there a way to include an external css file in a wiki (i.e. <link>) without having to embed the css within <style> tags in the page itself? Duke
