Do you mean this part of the tree here? +- env (class: org.jnp.interfaces.NamingContext) | | +- ejb (class: org.jnp.interfaces.NamingContext) | | | +- DataAccessFacade[link -> local/DataAccessFacade@23482138] (class: javax.naming.LinkRef) | For me it seems correct, or not? But the Nullpointer still is there... (I changed the lookup like you said) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123117#...
