[jboss-dev-forums] [EJB 3.0 Development] - trouble with deployment please help

Yucca Nel [http://community.jboss.org/people/Yuccanel] created the discussion "trouble with deployment please help" To view the discussion, visit: http://community.jboss.org/message/533220#533220 -------------------------------------------------------------- Hello, Google has no hits for the cause of the deployment failure so here is a detailed description of my war and the failure of the deployment. The war has a single ejb that is deployed in a war to make use of the new JEE features. I wish to deploy the war to test the ejb with cactus. My server log shows thw following and I am hardly surprised as it seems related to postgresql to which I am a newbie. at java.lang.ClassLoader.defineClass1(Native Method)     at
