Also how can you tell they are not executed.
javac will not return anything if the compilation is good. Try deleting the classfile and trigger the app. See if the classfile is created or not. Then you can confirm whether or not the javac is executed.
Similarly, do you have any System.out.println statements in the program to confirm that java is not called? |

The message is still in the queue.
I even had some display commands in java code to check that but, I dont even see them.
Both mqm and fmc are in the same group.
The QMGR and Trigger are both running under fmc. |

Remember the message does not disappear magically from the queue.
YOU are supposed to consume the message from the queue.
If your script mailnotificationscript.ksh does not consume the message it will stay on the queue.
NOW IF YOU ARE TRIGGERING A JAVA PROGRAM
did you make sure that your trigger monitor gets started in a shell/process with the right environment variables??
Otherwise you java program might just hang...
check ps -ef | grep java
What is your OS, MQ Version CSD?
Run a search on environment variables. I know I posted them before...(about 3 months ago...)
Enjoy  |

You need APAR IY43961, which is included in CSD04...
| Quote: |
When a Java application is triggered, it hangs while loading a
Java library when JIT is enabled (default behaviour). This is
caused by WebSphere MQ V5.3 blocking SIGTRAP on all threads and
including SIGTRAP in the signal mask passed to sigwait().
SIGTRAP is used by JIT for its own internal purposes.
|
and you need to set an env var in the shell from which you start the trigger monitor...
| Quote: |
This APAR introduces a new environment variable named
AMQ_NO_SIGWAIT_SIGTRAP to WebSphere MQ V5.3, which must be used
to make the change effective. Set this environment variable to
a value of 1 (and ensure it is exported) in the shell from which
you start the trigger monitor.
|
OR
you could not run the JIT compiler by
| Quote: |
Say export JAVA_COMPILER=NONE in the shell before starting the trigger monitor program. This will prevent the JIT compiler from running.

so do you want me to remove all the messages from the INITQ first and try it.
export JAVA_COMPILER=NONE
export AMQ_NO_SIGWAIT_SIGTRAP=1
export AMQ_SIGCHLD_SIGACTION=YES
runmqtrm -m FMCQM -q FMC.MAIL.NOTIFICATION.INITQ
i used the above 4 commands in a script file and started the trigger but still the same. |

So your application is starting, it's just not able to process messages on your queue.
