a question about rmi sample

hi jon,

In MyStatelessService.java, add following codes:

	public MyObject getMyObject();

then, in MyStatelessServiceImpl.java:

	public MyObject getMyObject() {
    	    return
((MySystem)CurrentPrevayler.getSystem()).getMyObject();
        }

finally, in RemoteCallServerTest.java, add following
test codes:

	MyObject myObject = myService.getMyObject();
        String value = myObject.getValue();

when i run the test case, throws the following
exception:

java.lang.ClassCastException

......

how to resolve such problem?

i have two scenarios:
1. at client, i only use MyObject to get Data, not to
perform any update operations.
2. at client, i will use MyObject to do any update,
they should be result in server side.

thanks!
