hi,

Please, I am running jbpm5.1.final, drools 5.2.0.final, HornetQ 2.0.0.GA.
When i try to create a remote node, when I call conf.configure(grid);, it throws a null pointer error:

private Map<String, GridServiceDescription> coreServicesMap;
    private Grid grid;
    private GridNode remoteN1;

public void createRemoteNode() {
              grid = new GridImpl(new HashMap<String, Object>());
              configureGrid1(grid,
                8000,
                null);
        GridNode n1 = grid.createGridNode("n1");
        grid.get(SocketService.class).addService("n1", 8000, n1);
        GridServiceDescription<GridNode> n1Gsd = grid.get(WhitePages.class).lookup("n1");
        GridConnection<GridNode> conn = grid.get(ConnectionFactoryService.class).createConnection(n1Gsd);
        remoteN1 = conn.connect();


    }


private void configureGrid1(Grid grid,
            int port,
            WhitePages wp) {
              System.out.println( "=================>Esta en configure grid"  );
        //Local Grid Configuration, for our client
        GridPeerConfiguration conf = new GridPeerConfiguration();
        //Configuring the Core Services White Pages
        GridPeerServiceConfiguration coreSeviceWPConf = new CoreServicesLookupConfiguration(coreServicesMap);
        conf.addConfiguration(coreSeviceWPConf);
        //Configuring the Core Services Scheduler
        GridPeerServiceConfiguration coreSeviceSchedulerConf = new CoreServicesSchedulerConfiguration();
        conf.addConfiguration(coreSeviceSchedulerConf);
        //Configuring the WhitePages 
        WhitePagesLocalConfiguration wplConf = new WhitePagesLocalConfiguration();
        wplConf.setWhitePages( wp );
        conf.addConfiguration(wplConf);
        if (port >= 0) {
            //Configuring the SocketService
            MultiplexSocketServiceCongifuration socketConf = new MultiplexSocketServiceCongifuration(new MultiplexSocketServerImpl("127.0.0.1",
                    new MinaAcceptorFactoryService(),
                    SystemEventListenerFactory.getSystemEventListener(),
                    grid));
            socketConf.addService(WhitePages.class.getName(), wplConf.getWhitePages(), port);


            conf.addConfiguration(socketConf);
          }

                    conf.configure(grid);// here produce null pointer exception


    }
