[xwiki-users] Error running XWiki Enterprise Manager on WebLogic 9.2

I am trying to set up XWiki Enterprise Manager on WebLogic 9.2 with an Oracle database. After deploying the application, and accessing it, I get the following error. The page still renders somewhat, but am unable to create wikis or do anything. Any help is appreciated, thanks.
