Hi,
The scrollable box uggh i which you display code snippets is never as wide
as its containing box and thus usually has both horizontal and vertical
scroll bars uggh. This is very bad ui design. Code is impossible to read
easily and the select and copy. Scroll bars should be avoided whenever
possible.
WDYT?

Hi,
Thanks for the compliments on xwiki ! Well, database porting should be
discussed on the developers list (
http://forge.objectweb.org/mail/?group_id=170 ) and added to the xwiki
page on databases (
http://www.xwiki.org/xwiki/bin/view/Dev/Database+Porting )
Concerning your errors, it doesn't look good.. it seems hibernate is
chocking while looking at the capabilities of the DB2 driver.. However
when I look at this (
http://www-128.ibm.com/developerworks/db2/library/techarticle/0306bhogal/03…
) it seems it should work.
Maybe it fails on something specific in the mapping.. So you might want
to remove each column from the xwiki.hbm.xml file until it works to see
what is the cause. Maybe a simple change in the mapping can make it work
with B2 without breaking xwiki..

Hi developers,
Artem, the google summer of code student working on the query API has a
first test implementation of an XPath like query implementation based on
the JackRabbit JCR package.
It's pretty neat.. Here is for example how to list child documents of a
page:
//*/*[@parent='Dev.IndependentQueryAPI'/@fullName]
or how to list all users
//*/*/obj/XWiki/XWikiUsers/@name - list all users
More info and feeback welcome here:
http://usunet.ru/xwiki/bin/view/Dev/IndependentQueryAPI
Ludovic
Artem is working on a Google Summer of Code project to build a
independent query API for XWiki..
This will define the new query languages for XWiki.. This has an
important impact on what xwiki will become..
Feel free to join the discussion on the API
http://jira.xwiki.org/jira/browse/XWIKI-98
Ludovic
It seems some people like jwebunit (I've never used it myself) and it may be
a good fit for xwiki functional tests.
It would then be possible to add some xwiki layer on top of it so that
functional tests could be edited in the wiki itself (a la fatcow/fitnesse).
Just an idea that I'm logging for fear of loosing it :-)

I'm using Tomcat 5.9 with XWiki 0.9.794. When i login to xwiki it throws an error like this,

Finally it says No FormBeanConfig found under 'skin'. If i'm correct something is missing in the struts-config.xml. But i'm not sure whether this is relevant to above exception
Renaming the webapp to 'xwiki' instead of 'xwiki-exo-0.9.840' didn't
solve the problem.

You should send this to the developers list.
It' seems tehre is an issue with class loading and hibernate..
It might be needed to play around with the jars
Also you should rename the webapp to 'xwiki' instead of 'xwiki-exo-0.9.840'
