Implementing synchronous request/response for an asynchronous service (JMS)

Question

Hi,
          <br>I've to consume soap/jms service from an external application.
          <br>The requirement is to consume it synchronous, meaning, the thread should wait for response.
          <br>
          I.e :
          <p>
          <i>void service(){
          <br> String id = generateCorrelationID();
          <br> Message msg = createRequest(id,...);
          <br> // send the message to the request queue
          <br> sendMesageToRequestQueue(msg);
          <br> Message responseMsg = null;
          <br> // search for the response, if is not found suspend the thread, then search again ...
          <br> do {
          <br> responseMsg = searchMessageInResponseQueue(id);
          <br> if(responseMsg == null) {
          <br> <Thread>.sleep(xxx)
          <br> }
          <br> } while (<messageIsNotFound>)
          <br> }</i>
          <p>
          <br>my application is J2EE 1.3.
          <br>Is it reasonable? am I going to face with deadlocks? locking issues? ...
          <p>
          Thanks,

Assuming synchronous receipt is absolutely necessary, I would rather use JMS synchronous call with timeout on QueueReceiver to receive message rather than spinning in a loop.
