JT400 - Replying to MSGW Job

Question

Is it possible to reply to a MSGW job in AS400 from JT400?
I've got the Job element and I can know if it's in MSGW status by Job.MESSAGE_REPLY_WAITING

Ex: normally I use "C" via WRKACTJOB

This is the code that works. I think it can be shortened and optimized.
There must be a better way!

public boolean answer(String answer) throws MyOperationException {
   if (answer == null || answer.length() > 1) {
      throw new MyOperationException();
   }

   MessageQueue msgq = new MessageQueue(as.getAS400(), QSYSObjectPathName.toPath(MyAS400.LIBRARY_LIST, "QSYSOPR", "MSGQ"));
   msgq.setSelectMessagesNeedReply(true);
   msgq.setListDirection(false);

   try {
      Enumeration m = msgq.getMessages();

      while (m.hasMoreElements()) {
         QueuedMessage msg = (QueuedMessage) m.nextElement();

         if (msg.getFromJobNumber().trim().equals(getNumber())) {
            msgq.reply(msg.getKey(), answer);

            return true;
         }
      }
   } catch (AS400SecurityException | ErrorCompletingRequestException | InterruptedException | IOException | ObjectDoesNotExistException ex) {
      ex.printStackTrace();
   }

   return false;
}

If you don't know the message queue, you can use ObjectList.
