Not my area so be gentle with me, but doesn't triggering work on Java if it's stand alone?

This is not difficult. You should be able to use MQ triggering for any language when a message arrives on a queue.
Write a script which is executed by the MQ trigger processing and the script can execute the $ java classname.class
Refer to the copious documentation about triggering in the library
http://www-306.ibm.com/software/integration/wmq/library/
As a Java programmer you should also investigate the use of MessageListeners

Vitor is correct... assuming you want to run a "main" class when messages arrive on the queue, you'd use triggering to start the "java" command with your class name.
And do NOT use trigger EVERY.

Yay me!

You might want to look at http://www.nynjmq.org which has a nice powerpoint on java triggering in last year's spring session...
Enjoy

Hi,
Triggering a program is no different from starting it from a command-line / shell. Just wrap it in a batch file or shell script.
| For Windows wrote: |
@echo off
setlocal
SET CLASSPATH=blah;blah;.;%CLASSPATH%
java com.acme.thing.App %*
endlocal |
| For Unix wrote: |
#!/bin/sh
SET CLASSPATH=blah:blah:.:$CLASSPATH
java com.acme.thing.App "$@"
|
Just remember that MQ passes the MQ TMC structure as the first parameter.
Regards,
