[Jython-users] PortableRemoteObject.narrow ClassCastException with JDK1.3 but no t JDK1.2.2

[Coleman, D. <don...@em...>]

I get a ClassCastException trying to narrow a reference to an EJB home using
JDK1.3 (on Win32).  This code works fine with JDK1.2.2 (on Win32).  I get
the same problem with jpython-1.1.  Am I doing something wrong or is this a
bug?

CODE THAT CAUSES THE PROBLEM

    jndiContext = InitialContext()
    object = jndiContext.lookup("emax.ContainerManager")
    # next line blows up with JDK 1.3 but not JDK1.2.2
    managerHome = PortableRemoteObject.narrow(object,
ContainerManagerHome.class)
    manager = managerHome.create()
