by Artem Melentev 18 Aug '05

18 Aug '05

Hi! Why XWikiHibernateStore.loadXWikiObject,Class,etc not in XWikiStoreInterface? Why XWikiHibernateStore.loadXWikiObject,etc not return loaded object like loadXWikiDoc? It does not allow load many objects in one hibernate session. (NonUniqueObjectException) Attached junit test show that i meen I need this for my QueryPlugin. (http://usunet.ru/xwiki/bin/view/Dev/IndependentQueryAPI) I am now compelled cache BaseClass in plugin. -- Artem Melentev, UralSU, CS301. http://usunet.ru/xwiki/ jabber: amelentev(a)jabber.ru | icq: 175349029

Task Manager
by Timothee Peignier 18 Aug '05

18 Aug '05

I've started creating a taks manager for xwiki. The objective is to have periodic tasks implemented as classic java class and as groovy script. I've started to write a basic one, based on quartz : http://www.xwiki.org/xwiki/bin/view/Dev/Tasks It's currently a simple object 'Task'[1], handle by 'XWikiTaskService'[2]. It support only cron like tasks and java classes. Task object are created/udpated upon xwiki object by a groovy script[3], which also allow to create/delete/pause/resume tasks. 1. http://www.xwiki.org/xwiki/bin/view/Dev/Task 2. http://www.xwiki.org/xwiki/bin/view/Dev/XWikiTaskService 3. http://www.xwiki.org/xwiki/bin/view/Dev/TaskList I'm currently watching to : - Improve the integration in xwiki - Add groovy implemented tasks - Add repeat/interval like tasks Any hints or help are welcome. Best regards, Tim -- http://people.tryphon.org/~tim/

xwiki installation not too friendly
by Jason Novotny 18 Aug '05

18 Aug '05

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

Re: [xwiki-users] Groups external to xwiki
by Ludovic Dubost 17 Aug '05

17 Aug '05

Hi Shawn, I think this is more appropriate in the developers list, even if I'm sure admins of xwiki's are interested in LDAP features. I'm also copying Alex who wrote the LDAP authentication plugin. Unfortunately he is on holidays so he won't be able to answer right away. I know he was thinking at a 'scripting' solution for groups management. Basically the idea would have been that you could directly call a group something like LDAPmygroup LDAPdept_htv The groovy script would then automatically translate the group name to the right query to make.. With LDAPmygroup maybe there would not even be a script needed as it would use normal ldap group.. But for LDAPdept_htv it would look for users having the htv property in the dept field. The script could also decide that if there is not LDAP in the name then it's a local xwiki group which would be allowed if a specific option is available in the preferences.. Now it might not be necessary to have scripting but would give more flexibility. I think Alex had some use cases where scripting would be really usefull. But it would be great to have him answer that.. If you can help writing this part this would be really great. Ludovic lauzon(a)us.ibm.com wrote: > Hi all.

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?

Re: [xwiki-users] xwiki backup / database conversion

Hi, I've posted our import/export scripts on http://www.xwiki.org/xwiki/bin/view/AdminGuide/Backup This should allow to load the default xwiki database in any xwiki compatible database. Let me know how it works.

xwiki portlets
by Jason Novotny 17 Aug '05

17 Aug '05

Hi all, I'm interested in supporting xwiki portlets for our GridSphere portal framework (http://www.gridsphere.org) It seems that xwiki is available for the Exo portal so I'm naively thinking it shouldn't be too hard to convert them to work in another portlet container. Can anyone help get me started if this is possible? Thanks, Jason

Integrating xwiki into IntelliJ
by dgrizzanti＠gmail.com 13 Aug '05

13 Aug '05

I'm attempting to integrate xwiki into IntelliJ to run, compile, and debug. I have Tomcat and a local copy of Xwiki running on my machine. I've obtained the xwiki source code from the SVN and I would like to be able to compile it to test. I haven't made any changes to the code as of yet, first I just want to get IntelliJ and xwiki working correctly together first. I'm not exactly sure how to setup xwiki in Intellij, that is my main question. I tried starting a New Project, choosing the xwiki/trunk/src as my directory for the source files. I wasn't sure where to put output directory so it just made a new folder inside the xwiki direcotory. When I attempt to Build (make project) I'm getting errors stating that duplicate classes are being found. I'm assuming I set it up wrong and I put the output directory in the wrong place or something. Does anyone know what I could be doing wrong and a good set of instructions to follow to get this working? Thanks
