Thread unserialized exception: NotSerializableException: java.lang.Thread

Question

hello experts,
i have this exception coming; seems to be coming from some thread but i removed all the threads from my code, i thought its because of some object which is still unserialized, i am not sure whether this is because of one unserialized object or its because of more reasons, please have a look:

this is coming  when i m accessing this method:
class BallServerImpl extends UnicastRemoteObject
implements BallServer
* @return an enumeration of all Balls as proxy objects
public Ball[] getAllBallProxies() throws java.rmi.RemoteException
     Ball[] locations1 = new Ball[hash.size()];
java.util.Enumeration iter = hash.elements();
int idx = 0;
while (iter.hasMoreElements())
     BallImpl impl = (BallImpl)iter.nextElement();
locations1[idx++] = new BallProxy(impl);
return locations1;
why this function is running fine when i m calling this from client unlike getAllBallProxies() nevertheless both are returning the same thing:
* @return an enumeration of all Balls as remote references
public Ball[] getAllBalls()
     Ball[] locations = new Ball[hash.size()];
java.util.Enumeration iter = hash.elements();
int idx = 0;
while (iter.hasMoreElements())
locations[idx++] = (Ball)iter.nextElement();
return locations;
the proxy Class:
* The Proxybouncing ball.
public class BallProxy implements Serializable,Ball {
* The Real bouncing ball.
public class BallImpl extends UnicastRemoteObject implements IBallRemote,Serializable
*load of thanks as this is "SHOW STOPPER",

Answer 1

that there was some thread there in BallProxy but i removed all from them and now testingIf you don't post the code people ask to see, you may never get a useful answer here.
P.S i didn't know that threads are not SerializedThe Thread class is not Serializable. Precision please.
Now i m updating the code, i needed the confirmationConfirmation of what?
and now trying to avoid them.Them?
But what if i need them.Them?
Please make the effort to express yourself clearly. You've already been told you're not making much sense and you haven't done anything about it.
how can we make serialized?The concept of serializing a Thread makes no sense whatsoever. You don't want to do it. You don't need to do it. You can't do it. It wouldn't work if you could do it.
Somewhere or other you have a class member that is a reference to a Thread. Remove it or make it transient. If you post the code somebody may help you. If you don't, nobody can possibly do that.
