158 11. Client Server Architecture

To get the remote clients identity, the concept is applied inside the SO and

overrides the platonic RO method. First, the remote method to call the

remote client is implemented and externally hidden as private:

private RemoteMethod<Object> getIdentity

= new RemoteMethod<Object>()

{ @Override

public Object call() throws RemoteException

{ return remoteObject.getIdentity(); }

};

Then, the actual method can be published with

final public Object getIdentity()

{

RemoteCall<Object>

remoteCall = new RemoteCall<Object>( getID );

Object remoteID = null;

try { remoteID =

remoteCall.get( maxWaitForRemoteObject );

// validate remote value ...
