I tried to follow this scheme but now I'm getting a different problem,

Then after little browsing i came across
http://jira.codehaus.org/browse/PLX-331 and then tried,
1. Build plexus-servlet locally.
2. Build xwiki-plexus locally (with the new version of plexus-servlet)
3. Build & tried `mvn jetty:run` on xwiki-webdav
But still it gives the same error.
I am so stuck here and need your help to fix this.
Simply, i need to know how to properly initialize the componentManager.
The procedure used in
(/trunks/xwiki-platform-tools/xwiki-shared-tests/src/main/java/com/xpn/xwiki/test/AbstractXWikiComponentTestCase#getComponentManager())
doesn't seem to work for me.
Please help.
