Thank you for your very thorough answer.  It gave me a lot of pointers 
and help to figure this out (which gave me the vocabulary to discover 
how others discussed this previously without me understanding it to be 
the issue :)

My goal was to provide the Java program the ability to detect and handle 
the MSGW situation without a human needing to use a green screen.  By 
using a second AS400 object (hence a different prestarted job answering) 
I can watch the job with something like

Job j = new Job(systemi, job.getInternalJobIdentifier());
do {
   Thread.sleep(1000);
   j.loadInformation();
} while 
(Job.ACTIVE_JOB_STATUS_WAIT_MESSAGE.equals(j.getValue(Job.ACTIVE_JOB_STATUS)) 


Either a default response is already known or a developer can be 
presented with formatted versions of j.getCallStack(Job.INITIAL_THREAD) 
and jobLog.getMessages(0, jobLog.getLength()) to determine a specific 
response in the situation.

I assume for now that the inquiry message is in QSYSOPR (our guru is on 
vacation), so this snippet will send the response and delete the message:

           String jobId = getJobId(job.getNumber(), job.getUser(), 
job.getName());
           MessageQueue queue = new MessageQueue(systemi, 
"/QSYS.LIB/QSYSOPR.MSGQ");
           Enumeration messages = queue.getMessages();
           while (messages.hasMoreElements()) {
               QueuedMessage message = (QueuedMessage) 
messages.nextElement();
               message.load();
               if (message.getType() == AS400Message.INQUIRY) {
                   message = queue.receive(message.getKey(), 0, 
MessageQueue.SAME, MessageQueue.ANY);
                  
                   String number = message.getFromJobNumber();
                   String user = message.getUser();
                   String name = message.getFromJobName();
                  
                   if (jobId.equals(getJobId(number,user,name))) {
                       System.out.println("Got it!");
                       queue.reply(message.getKey(), response);
                   }
               }
           }
...
   private static String getJobId(String number, String user, String 
name) {
       return number + "/" + user + "/" + name;
   }

Hopefully this can help others, and if there is comments I'd like to 
hear them :)  Now I just need to get this to production quality :-S

Thanks again.
