XWiki on eXo?

Hi I have downloaded the latest XWiki as eXo war and tried to deploy it. I was able to add it as portlet in the portlet administration. (Click on "import portlet" works fine). But when I try to actually add it to a container (Click on "add portlet") I can see xwiki in the list and also select it but then I get exceptions. (See the two screenshots I attached to this mail) Here is what I have done: 1. Install J2SDK 1.5.0.6 and set JAVA_HOME 2. Install the latest eXo-tomcat (Version 1.1.1 or so) 3. Install MySQL (the latest MySQL 4.1.x) 4. Create a user xwiki/xwiki in it 5. Dump the XWiki SQL script into it 6. Grant all privileges of user xwiki to that database 7. Rename the eXo download thing to xwiki.war 8. Throw that into /exo-tomcat/webapps 9. Download the MySQL driver version 3.1 (or so) and throw the jar into the common/lib directory of tomcat 10. Start exo-tomcat 11. Log in as exoadmin and import new portlets -> the folder xwiki with item xwiki appears 12. Log in as exo and try to add the xwiki to a container That is the moment where I get the exceptions as shown in the screenshots. Any ideas? Thanks scrut
