[Spread-users] Dumb Java question

I seem to be laboring under a mis-understanding of how this stuff is
supposed to work. I have created simple client and server programs in Java
and have set the server up to join a group with a bogus name ("Spanky").
However it gets all of the messages posted to two different groups
("Archer", "Janeway") by the client regardless. Does this mean that I (the
server) have to look at each message that comes through to check for a
group to which I am interested. If this is the case doesn't this defeat
the purpose? What am I missing here?

    SpreadConnection connection = new SpreadConnection();
    connection.connect(InetAddress.getByName(address), port, user,        
                     false, false);
    String privateName = connection.getPrivateGroup().toString();
    SpreadGroup group = new SpreadGroup();
    group.join(connection, "Spanky");
    in = connection.receive();

            SpreadConnection c1 = new SpreadConnection();
	    SpreadConnection c2 = new SpreadConnection();
	    SpreadGroup g1 = new SpreadGroup();
	    SpreadGroup g2 = new SpreadGroup();

                port, user, true, true);

                port, user, true, true);

	    g1.join( c1, "Archer" );
	    g2.join( c2, "Janeway" );

            SpreadMessage out1 = new SpreadMessage();
            SpreadMessage out2 = new SpreadMessage();


            for( int i = 0; i < 1000; ++i )
                o1.setMessage( "Starship Enterprise : " + i );
                o2.setMessage( "Starship Voyager : " + i );
                c1.multicast( out1 );
                c2.multicast( out2 );

Any insight would be helpfull
