Jxta não encontra outros peers

Assuntos Gerais
#1

Bem, tenho um exemplo de descobrir outros peers no netPeerGroup, não sei se esse netPeerGroup corresponde ao grupo da rede local ou um grupo global, pois o PeerGroupID é sempre o mesmo, mas se for isso, eu deveria encontrar outros peers, e isso não está funcionando. Já chequei os jars, liberei as portas específicas do windows e do roteador, mas continuo com o mesmo problema, se alguém puder me ajudar com a parte das portas é só postar, porque não sei se liberei corretamente.
Aqui vai o código que testei:

[code]import java.io.IOException;
import java.util.Enumeration;
import net.jxta.discovery.DiscoveryEvent;
import net.jxta.discovery.DiscoveryListener;
import net.jxta.discovery.DiscoveryService;
import net.jxta.exception.PeerGroupException;
import net.jxta.id.IDFactory;
import net.jxta.peer.PeerID;
import net.jxta.peergroup.PeerGroup;
import net.jxta.peergroup.PeerGroupID;
import net.jxta.platform.NetworkConfigurator;
import net.jxta.platform.NetworkManager;
import net.jxta.protocol.DiscoveryResponseMsg;
import net.jxta.protocol.PeerAdvertisement;

public class DiscoveryDemo implements Runnable, DiscoveryListener {

static PeerGroup netPeerGroup = null;
private DiscoveryService discovery;
static NetworkConfigurator netconfig;

// start the JXTA platform
private void startJxta() throws IOException, PeerGroupException {
    NetworkManager manager = new NetworkManager(NetworkManager.ConfigMode.EDGE, null);
    PeerID pid = IDFactory.newPeerID(PeerGroupID.worldPeerGroupID, new String("nada").getBytes());
        
    manager.startNetwork();
        netconfig = manager.getConfigurator();
        netconfig.setPeerID(pid);
        netconfig.setTcpPort(9710);
        netconfig.setTcpIncoming(true);
        netconfig.setTcpOutgoing(true);
        netconfig.setTcpEnabled(true);
        netconfig.addRdvSeedingURI("tcp://123.123.123.123:1234");
        
        netPeerGroup = manager.getNetPeerGroup();
        System.out.println(netPeerGroup.getPeerGroupName());

    // Get the discovery service from our peer group
    discovery = netPeerGroup.getDiscoveryService();
}

/**
 * 35 * This thread loops forever discovering peers 36 * every minute, and
 * displaying the results. 37
 */
public void run() {
    try {
        // Add ourselves as a DiscoveryListener for DiscoveryResponse events
        discovery.addDiscoveryListener(this);

        while (true) {
            System.out.println("Sending a Discovery Message");
            // look for any peer
            discovery.getRemoteAdvertisements(null, DiscoveryService.GROUP,
                    null, null, 0, null);

            // wait a bit before sending next discovery message
            try {
                Thread.sleep(60 * 1000);
            } catch (Exception e) {
            }

        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

/**
 * 3 * by implementing DiscoveryListener we must define this method 4 * to
 * deal with discovery responses 65
 */
public void discoveryEvent(DiscoveryEvent ev) {

    DiscoveryResponseMsg res = ev.getResponse();
    String name = "unknown";

    // Get the responding peer's advertisement
    PeerAdvertisement peerAdv = res.getPeerAdvertisement();

    // some peers may not respond with their peerAdv
    if (peerAdv != null) {
        name = peerAdv.getName();
    }

    System.out.println("Got a Discovery Response ["
            + res.getResponseCount() + " elements] from peer : "
            + name);

// printout each discovered peer
PeerAdvertisement adv = null;
Enumeration enume = res.getAdvertisements();

    if (  enume != null) {
        while ( 
            enume.hasMoreElements()) {

adv = (PeerAdvertisement)
enume.nextElement();
System.out.println(" Peer name = " + adv.getName());
}
}
}

static public void main(String args[]) throws IOException, PeerGroupException {
    DiscoveryDemo myapp = new DiscoveryDemo();
    myapp.startJxta();
    myapp.run();
}

}[/code]
