No qizhirui, you have not read anything on MQ trigger....your post tells it all...
Read, and then ask your relevant doubts.

why do you say that" i have not read anything on MQ trigger....",just by your own judgement. If you say like that, it is a shame to me .In a fact , i print some materials about the MQ trigger.

I get some material from this link .i will post my questions here |

MQ Triggering is not written in Java....triggering is simply settings on the queues which can call java applications wrapped in an exe or bat etc.
You should pick up some of the pdf's or primer to see a simple implementation of a trigger....or search the forum....i think i remember someone giving the steps required for triggering.

Hey qizhirui
The thing about MQ is you may not understand everything you read at the first shot. Read the manual, take a break and read it again, then again and then again. Each time you read the doc you will gain more and more insight into whats being said and most importantly why something is like that. This doesnt mean you have to read something 100 times before posting a question here but you get better replies if the folks here can know that you did your part and still you are not able to grasp something.
Just my 2 cents
Cheers

To summarize a bit.
A program that is triggered is not any different from a program that is not triggered - they both get messages from a queue using the same code and logic. The only significant difference is where they get their configuration - a properly written triggered program will get it's queue name configuration and qmgr information from the MQTMC2 structure that is passed to it from the trigger monitor.
A triggered program can be written in any language.
A trigger monitor program is just another MQ application, that reads messages from an initiation queue, and has the responsibility to launch the program described in the initiation message and pass it an MQTMC2 message on the command arguments.
A trigger monitor can be written in any language.
The presupplied trigger monitors are not written in Java. Because of this, they must trigger something that starts a JVM in order to invoke Java code. The easiest way to do this is by using a batch or shell script to isolate the JVM invocation from the Process definition - as JVM invocations can be very long and thus run out of room in the process definition.

i guess you're looking for this:
1. define an initial queue for QMGR to put meta-data into;Â
DEFINE QLOCAL('QL.TRIGGER_MSGS') REPLACE
2. define a process for trigger monitor to run once triggered;Â
DEFINE PROCESS('MY_PROCESS') REPLACE + USERDATA('PARAM1 PARAM2') + APPLICID('c:\mypath\myprog.exe')
3. define a qlocal with trigger type, initial queue name, process name which i just defined;Â
DEFINE QLOCAL('QL.IN') REPLACE +
TRIGGER TRIGTYPE (EVERY) INITQ('QL.TRIGGER_MSGS') PROCESS('MY_PROCESS')
4. start runmqtrm to monitor if the initial queue has been put something into, and run the process if it does.Â
start runmqtrm -m QMN -q QL.TRIGGER_MSGS |
