This is the way to go I think but you need to wait and notify on the queue as well as
have synchronized blocks.
Be sure that your queue is thread safe (Vector or some synchronized Set,Map). Don't
use thread priority this is not well specified for the JVM. You don't have any control
over how the thread priority will work.
/** Thread that sends all message to the clients */
public void run() {
if(queue.size() == 0) {
synchronized(queue){
try{
queue.wait();
}
catch(InterruptedException ie){}
}
}
message = queue.dequeue();
proccessMessage(message);
}
public void sendToClients(Message message) {
queue.enqueue(message);
synchronized(queue){
queue.notifyAll();
}
}

Hi,
I am not sure I understand your issue completely, but for the following
issue:

Have you tried something along these lines ?
/** Thread that sends all message to the clients */
public void run() {
if(queue.size() == 0) {
wait();
}
message = queue.dequeue();
proccessMessage(message);
}
/** method used to add items to the queue */
public void sendToClients(Message message) {
queue.enqueue(message);
notifyAll();
}
Cheers,
Brad
