Hi, I have just installed the jar in my WebLogic/Oracle ear starting to test it. I have reached a problem that was solved by adding <property name="query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</property> to the hibernate config. And Now I am getting the attached exception. The tables where created in the DB and XWIKIRCS was even filled with 16 records, so it looks like the DB connection is working. Even tough the exception where thrown, the XWiki WebHome was opened (even tough when I have clicked the administration I have got exception on page.) Please assist. Thanks a lot.
