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     } 17:06:23,521 ERROR [STDERR] java.lang.NullPointerException 17:06:23,523 ERROR [STDERR]     at org.drools.grid.timer.impl.CoreServicesSchedu lerConfiguration.configureService(CoreServicesSchedulerConfiguration.java:23) 17:06:23,526 ERROR [STDERR]     at org.drools.grid.conf.impl.GridPeerConfigurati on.configure(GridPeerConfiguration.java:22) thanks in advance -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/623876#623876] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
