Category: None Group: v3.2 Status: Open Resolution: None Priority: 5 Submitted By: Ralf Zimmermann (rz1911) Assigned to: Nobody/Anonymous (nobody) Summary: ClassCastException using JNDI with scoped Classloading Initial Comment: Hello, I try to access an shared object which is bount to JNDI from two web applications within separate EARs using scoped class loading. This results in an ClassCastExecption. When I try to access the shared object from another VM everything works fine. It also works fine if the shared object classes are placed in the default/lib directory. I think this is because there is an optimization that no remote calls are used within the same VM. But this optimization is only OK for classes loaded from the same class loader. (The same problem seems to cause ClassCastExeptions if you call EJBs via remote interfaces from diffent EARs using scoped class loading) To reprodurce the failure deploy the attached test files server.ear and client.ear. Open http://localhost:8080/server (this creates and binds the shared object an sets a test value). After that open http://localhost:8080/client (This causes the ClassCastException (see below). Source files are attachted, too.
