Explanation/Reference:
Note:
* RemoteRef represents the handle for a remote object. A RemoteStub uses a remote reference to carry out a remote method invocation to a remote object.
* invoke
public Object invoke(Remote obj,
Method method,
Object[] params,
long opnum)
throws Exception
Invoke a method. This form of delegating method invocation to the reference allows the reference to take care of setting up the connection to the remote host, marshaling some representation for the method and parameters, then communicating the method invocation to the remote host. This method either returns the result of a method invocation on the remote object which resides on the remote host or throws a RemoteException if the call failed or an application-level exception if the remote invocation throws an exception.
