Could not find group implementation in JXTA

[Gary Kim]

Hi,
I want to cry, I really do not know what is wrong with the code. Could anyone please please tell me wat is wrong. There is a bug somewhere in there that I cant seems to find..

import net.jxta.id.IDFactory;
import net.jxta.document.AdvertisementFactory;
import java.util.Enumeration;
import net.jxta.discovery.DiscoveryService;
import net.jxta.exception.PeerGroupException;
import net.jxta.peergroup.PeerGroup;
import net.jxta.peergroup.PeerGroupID;
import net.jxta.protocol.PeerGroupAdvertisement;
import net.jxta.protocol.ModuleImplAdvertisement;
import net.jxta.peergroup.PeerGroupFactory;

public class groupsCreation {

static PeerGroup myPeerGroup= null;
private DiscoveryService discovery;

public static void main(String args[]) {

groupsCreation myapp = new groupsCreation ();
System.out.println("Starting group Creation");

myapp.startJxta();
//myapp.groupsInLocalCache();
myapp.createGroup();
myapp.groupsInLocalCache();
//System.exit(0);

}

public void startJxta() {

try {
myPeerGroup = PeerGroupFactory.newNetPeerGroup();


}
catch(PeerGroupException e){

System.out.println("Failed creation");

}

discovery = myPeerGroup.getDiscoveryService();

}

private void groupsInLocalCache() {

System.out.println("local cache (cm directory)");

try {
PeerGroupAdvertisement adv = null;
Enumeration enum = discovery.getLocalAdvertisements(discovery.GROUP, null, null);

if(enum!=null) {

while(enum.hasMoreElements()){

adv = (PeerGroupAdvertisement)enum.nextElement();
System.out.println(adv.getName() + ", group id =" + adv.getPeerGroupID().toString() + ",ModuleSpecId = " + adv.getModuleSpecID().toString());



}

}

else {System.out.println("No Group Exist");
}


}
catch (Exception e){}

}

private void createGroup() {

PeerGroupAdvertisement adv=null;
ModuleImplAdvertisementmyGroupImpl = null;

System.out.println("Create Peer Group Advertisement");
PeerGroup tempPeerGroup = null;


try {

myGroupImpl = myPeerGroup.getAllPurposePeerGroupImplAdvertisement();


//System.out.println(pid.toString());
}catch(Exception e) {

System.out.println(e.toString());

}

adv = (PeerGroupAdvertisement)AdvertisementFactory.newAdvertisement(PeerGroupAdvertisement.getAdvertisementType());
adv.setName("Create Test2");

PeerGroupID pid = (PeerGroupID)IDFactory.newPeerGroupID();
adv.setModuleSpecID(myGroupImpl.getModuleSpecID());
adv.setPeerGroupID(pid);
adv.setDescription("asd");

try {

discovery.publish(adv, discovery.GROUP);
discovery.remotePublish(adv, discovery.GROUP);
System.out.println("Publishing advertisement");
}

catch(Exception eee) {
System.out.println(eee.toString());
}


try {
System.out.println("About to create group");

PeerGroup pg = myPeerGroup.newGroup(adv);

System.out.println("Succeeded creating group");


}catch(Exception eeee)
{
System.out.println(eeee.toString());
     }

        }

}

I hope it would be too messy to read....

I left out something it seems that it could not find the "Group Implementation"
thank you
