Hi Ludovic,
I've been working on assembling a servlet using your webdav code, xwiki-core
and other relevant dependencies. Although i could deploy the WebDAV servlet,
I have few things I can't get pass,
* What do I need to do so that once deployed the webdav servlet will use an
instance of hsqldb ( like the stand-alone xwiki installation ) ?
* Currently when I make a request to the servlet, I get the following error,
2008-04-02 20:21:19,597 [http://localhost:8080/DAVServer/]
[http-8080-Processor24] ERROR [/DAVServer].[DAVServlet] -
Servlet.service() for servlet DAVServlet threw exception
java.lang.NullPointerException
at java.util.Hashtable.put(Hashtable.java:396)
at com.xpn.xwiki.web.Utils.prepareContext(Utils.java:274)
at

at
com.xpn.xwiki.plugin.webdav.XWikiDavServlet.service(XWikiDavServlet.java:340)
Tracking down reveals that the code in Utils,
ComponentManager componentManager =
(ComponentManager)
engine_context.getAttribute(ComponentManager.class.getName());
context.put(ComponentManager.class.getName(), componentManager);
Is throwing a null-pointer exception where componentManager is NULL. I
believe this has something to with plexus, could tell me how to overcome
this ?
I'm sort of stuck at this point, any help is really appreciated.
Btw, Ludovic, how were you able to test your code ?
Thanks a lot.

This is new code in XWiki 1.3+
Just add one line to test for the NULL and not put it in the map

Well this is a quick and probably non-working workaround. The correct
way is to initialize Plexus in XMLRPC mode too. Right now it's
initialized in Servlet mode only I think.
For example if you need to do any velocity stuff (which is the case in
the XMLRPC API I believe when retrieving a page's rendered content) it
won't work since Velocity rendering is now done in a component.
I guess I'll have to look into this to do a proper Plexus
initialization in XMLRPC mode.

At this point it does work for the GWT RPC. Now it's sure as there are
more components all XWiki function rely on we will need to have it
really working
The case for Asiri is not for XMLRPC but for WebDAV which should not
make use of velocity.
