    can I use same persistence unit name in multiple wars?

    llraj Newbie

      I have 2 wars that use the same PU name in their respective persistence.xml. This works in Glassfish v2.1.1 and v3 however I get a component already exists error in JBoss 5.1.0GA

       

      The first war is deployed successfully but the second war fails deployment with below error,
