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'

Hi XWiki devs,
At Mandriva we have the need for a class property type that would be
able to handle dynamic lists. Well, the DBList properties are already
dynamic, but we'd need something more dynamic.
Usage examples:
* apply some filter to a list of results fetched from the database,
* translate the DBList values returned by a SQL query before presenting
them to the user
* build lists from other sources than the database (from a web service
call etc.)
Such lists would be built by a Velocity or Groovy script, declared as an
attribute of the class property. What do you think of the feature? Do
you have any suggestion on the way it should be implemented? We could
either create a new Java type "DynamicList" + new wiki table
xwikidynlistclasses, inspired by the "DBList" Java type, or transform
the DBList into a "DynamicList" that would handle either Hibernate SQL
queries, or Velocity/Groovy scripts. That would be handy also to have
the possibility to specify the name of the document containing the
script to be executed, if the script is to be reused by several classes.

Hello,
Has anyone here had experience developing a JXTA or Eclipse RCP application?
I have a few questions:
JXTA and other protocols:
Is there anyway to autoconfigure during the first launch of a
JXTA-enabled program instead of showing the user the configurator?
(start with default settings and put the configurator into a settings
menu?)
Is Rendezvous in JXTA the same as Apple's Bonjour (formerly known as
Rendezvous) ?
http://en.wikipedia.org/wiki/Bonjour_%28protocol%29
Eclipse RCP:
What constraints are there to developing Eclipse plugins as opposued
to raw Java applications?
If my application is based on a Model-View-Controller pattern, can I
simply develop the model for my application, and then later develop an
RCP plugin for the View/Controller?
Thanks for any help,
Kevin Chiu
