/**
 * Test the serialization of the EJBObject's stub using the Handle object.
 * 
 * A handle is a serializable object that knows how to get back to the
 * original Remote EJB object (it's now a subt, but it can get the stub).
 * This handle has the "smarts" to communicate with the server and get back
 * something that is just the same as the EJB object you had before (might not
 * be the same EJB object, but the client will never be able to tell the difference).
