Hi , in first time sorry for mi english ! I have multiple ear's sharing one EJB . This EJB is deployed in one each ear . EAR-A war ejb-a ejb-shared EAR-B war ejb-b ejb-shared I need only one instance/reference of ejb-shared , and I use @LocalBinding(jndiBinding="X") for that in the ejb's in ejb-shared.jar . So , that's work fine for mi in JBoss 4.2.2.GA , no errors , and only one instance of my ejb-shared is reference for all ear's . But , when migrate to JBoss 5.1.0.0.GA that's not work and I have the "NameAlreadyBoundException " for all ejb in the ejb-shared.jar in the second deployed EAR . I can't find help about that . can anyone help me? thank you very much in advance!! View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254586#...
