RE: Passing messages from RPG back to java using Message Queue

Hi
I am running this java program outside AS400, it is part of web application running on Windows and Apache tomcat.

I did add lot of debug code to see what is happening,
But the method
Enumeration e = queue.getMessages();
gives me empty enumeration, but i did check the message queue is present in QTEMP library, but the messages are not getting through to Java,
How do i find this issue, and it only happening on 1 AS400 machine, i have this web application running against atleast 10 other AS400 machine with out and issue, but on this particular As400 i get this error, what may be the reason??

A$HI$H

I'd also add in some debug logging code (log4j?) in your
code. I use
log4net, but given its origins as a port of log4j I'd
assume log4j works
roughly the same way. I would expect to see your code more
like
(//logging call):

// clear the queue for any previous message
queue.remove();
log.debug("Cleared"); //logging call

// call RPG program
boolean rc = pcml.callProgram(pcmlFile);
log.debugFormat("Call returned {0}", rc);
//logging call

//if call is successful
List messages = new ArrayList();
if (rc)
{
Enumeration e = queue.getMessages();
if (!E.hasMoreElements())
log.Warn("e has no elements"); //logging call

while (e.hasMoreElements())
{
QueuedMessage msg = (QueuedMessage) e.nextElement();
log.debug("Got message"); //logging call
msg.load();
messages.add(msg.getID() + " " +

StringEscapeUtils.escapeJava(msg.getText()) +
"|" +

StringEscapeUtils.escapeJava(msg.getHelp()));
}
}
else
log.Warn("Call was unsuccessful"); //logging
call

Then I'd just say crank up the loglevel and see what
falls out.
