Problem notifing objects.

Question

One object do that:
boolean ack_recibido = peticion.enviarRequest(request,this);
          if (ack_recibido==true)
               try {
                    wait(timeout); 
                    System.out.println("timeout passed");
                    return reply;
               } catch (InterruptedException e) {
                    e.printStackTrace();
          return null;and another do that:
     public void devolverRespuesta(byte[] reply) {
               System.out.println("estamos en la clase peticiones");
               System.out.println(new String(reply));
               arrayComandosRecibidos[contadorComandos-1].setReply(reply);
               arrayComandosRecibidos[contadorComandos-1].notifyAll();
          }arrayComandosRecibidos[contadorComandos-1] is the objectt which is waiting, and setreply works, but it not wake up until timeour.
�How can I wake up the onject if notify does not work?
Thanks for the answer.

Answer 1

arrayComandosRecibidos[contadorComandos-1] is the objectt
which is waitingNote that it is not the object that is waiting, but the thread.
When calling wait on a given object (this in your case), the current thread waits until another thread calls notify(All) on this object (or until given timeout expires.)
So what threads are implied in your code ?
Are you sure that one thread calls wait, and then another thread calls notifyAll (before timeout expires) ?
