Problem with FAQ Tutorial

Hello, all. Has anyone been able to successfully create an FAQ application using Oracle as their database? I have not been able to get very far because the following error occurs when I try to access the XWiki.XWikiClasses document: Error number 4001 in 4: Error while parsing velocity page XWiki.XWikiClasses Wrapped Exception: Invocation of method 'getClassList' in class com.xpn.xwiki.api.XWiki threw exception com.xpn.xwiki.XWikiException: Error number 3223 in 3: Exception while searching class list Wrapped Exception: could not execute query @ XWiki.XWikiClasses37,32 It looks like the root exception is: java.sql.SQLException: ORA-00932: inconsistent datatypes: expected - got CLOB I installed xWiki version: 1.0-rc-4.3161 on Windows and am using the last version of OracleXE 10.2.0 Any help is greatly appreciated. TIA - Ciao, Dixie.
