I see that when using Reference Messaging IBM provides the user exits in C++. Are there any exit routines written in Java or is it not possible to implement Reference Messaging with Java?

1) Can't you simply build the MQRMH structure in Java, and then write a Java routine that appends the file when the header message is sent across the channel?


2) I don't believe you can do this with JMS, but if this is simply sending a header message across a channel to another queue, isn't it ok to write the exit routines in Java or is there some reason you can't?

Thanks for your help,

B

I don't think you can write any server-side exits in Java, because the queue manager does not have an associated JVM - there's nothing to execute the java code within.

You could write a C exit that used JNI to call Java code, though.

The reference message exit is packaged with WMQ.
So if the dafault behavior is ok with you just add MQRMH header in your MQ Java program.
