I'm using Tomcat 5.9 with XWiki 0.9.794. When i login to xwiki it throws an error like this, 18:14:40,479 ERROR http-8081-Processor23 http://localhost:8878/xwiki/bin/view/Ma in/WebHome AssertionFailure:<init>:22 - an assertion failure

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

Re: [xwiki-users] Looking for forwarding in Velocity script

Hi Xavier, I just wanted to let you know that we have a couple of conference projects and I would be interested in discussing / working in this area with you and any other interested users and developers. I am working with a small team to build an event wiki for Connexions which will take place in October and I am porting and extending some networking features that allow organisers to match conference attendants and experts among themselves. I started writing the user stories for this (in French), we could share and discuss them if you are interested. Luis.

Fwd: [xwiki-users] Question about authentication
by Luis Arias 28 Jul '05

28 Jul '05

This is probably best in the developers list. Maybe Alexis can give you a hand with this. From what I know the user documents *do* have to exist in the wiki. But I'm afraid I don't know enough to point about the LDAP implementation to point you out in the right direction... Luis. ---------- Forwarded message ---------- From: Matthew Conway <conway(a)tripadvisor.com> Date: Jul 28, 2005 4:47 PM Subject: [xwiki-users] Question about authentication To: xwiki-users(a)objectweb.org I'd like to be able to use XWiki with an alternate source for user authentication and I thought creating my own auth service might do the trick. However, on further thought, I'm not sure how this would work - doesn't the XWiki user document still need to exist as a place to store user settings (e.g email notification plugin stores an object there)? I dug around a bit in the LDAP service code, and don't see anywhere where it creates the xwiki user document, so I'm wondering what I'm missing. I was thinking that maybe it should should auth the user then create the user doc if it doesn't already exist. I guess the code/pages I have that register that user could also send a message to xwiki to create the user, but for LDAP user management clients that may not be possible, so I must be missing something. Is there a better way to do auth that I don't know about? Our user data is in a set of DB tables.
