eXo xwiki integration

Hello, I have problems integrating xwiki in exo platform. I'm not sure if this is the right list to ask, but had to pick one, please tell me if I chose wrong. So, here is the context : I'm using eXo sources dated 20070108 and xwiki 1.0 Beta 2. xwiki.war is placed in webapps, xwiki.conf has been modified to set exo usage. portlet.xml seems ok, web.xml has been modified to add the portlet/servlet wrapper. I modified wxiki context from / to /xwiki. With all this, xwiki portlet appears in eXo import portlet. The database has been loaded from the script 1.0-beta1, in a database named xwiki, accessible with user xwiki/pass xwiki. When I try to prompt xwiki in eXo, I have a "You are not allowed to ... message, end hidden by black squares". I'm connected with exoadmin. Just to be sure, i logged to xwiki (standalone) and created a exoadmin user. But I still get this kind of errors : "[INFO] XWikiRightServiceImpl - Access has been denied for (xwiki:XWiki.exoadmin,Main.WebHome,view): access manager denied right" along many stack traces about documents that could'nt be instanciated because no row with id xyz found in database. Looks like a bad filled database to me. What did I do wrong ? Any thing I didn't do ? What do I have to do ? Sincerely yours, Nicolas Pays.
