Idea for xwiki functional tests
by Vincent Massol 04 Aug '05

04 Aug '05

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 :-) -Vincent

Dynamic lists
by Stéphane Laurière 01 Aug '05

01 Aug '05

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. Stéphane and Christophe

JXTA
by Kevin Chiu 01 Aug '05

01 Aug '05

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
