If you compile the stubs/ties for a remote object, with the -poa flag turned on,
you cannot use the PortableRemoteObject.toStub() call to get the stub for that object. The toStub() calls returns a class cast exception. On the other hand, if you compile it without this flag turned on, toStub() returns the Stub object.

Here's the ClassCastException that is seen when using the toStub() call.

is it friday yet ;) java -Dorg.omg.CORBA.ORBClass=com.sun.corba.ee.internal.POA.POAORB -Dorg.omg.CORBA.ORBSingletonClass=com.sun.corba.ee.internal.corba.ORBSingleton -Dorg.omg.CORBA.ORBInitialHost=javalite -Dorg.omg.CORBA.ORBInitialPort=10000 IsLocalTests

I have also attached the test code that I used.

A simple rmi-iiop Client/Server program that compiled with "rmic -iiop -poa ..."
still yielded the same exception when the Server started.
