Your right that was not needed. See posting http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4013125#... for how I got it running by setting isTransactionEnabled to false and isCurrentSession enabled to false on jboss 4.0.5ga. However, this does not solve the original issue. Whats up with JTA vs. CMT transaction configuration? Is this resolved? Has anyone figured out how to properly configure transactions for 4.0.5ga? Please can anyone respond to this one, it is all that stands in the way of getting cvs trunk to run on 4.0.5ga More on subject http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4013125#...
