Hi, Can anyone tell me which are the differences between jboss-jca.jar implementations of JBoss AS 4.0.4 and 4.0.5. I'm using Spring 2.5 + Hibernate JPA impl and I run into a name not found exception with a Oracle datasource in JBoss 4.0.4. If I change de jboss-jca.jar of the 4.0.4 with the one of the 4.0.5 all works fine. I have the same problem with 4.2.2. Does anyone know the differences between them, or the dependencies differences? Thanks in advance. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4143657#...
