Hi Jason, I don't think the null pointer exception is caused by EJB RC9 but rather by Hibernate 3.2.0.GA that ships along with JBoss 4.0.5GA. To get it to work it will require you to manually patch the fromClause.java (very simple patch, only 1 or 2 lines). I have entered a bug in the Hibernate JIRA (http://opensource.atlassian.com/projects/hibernate/browse/HHH-2159), if you want it fixing, please vote for the issue. Cheers, Andy View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993742#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
