Hi, we are planning to migrate our whole MQ from our LINUX server to MQ Appliance. Besides having MQ installation and QMs on our LINUX server, we also have a Java code running (jar files) which we use to do some manipulation on MQ messages.

we have a doubt if we migrate our Queue Managers to MQ appliance, can we also migrate our JAR files as well to MQ appliance without losing any of its functionality?

You cannot run user code on the MQ Appliance.

The IBM MQ Light API can be used on the appliance (from MQ V8.0.0.5).

Your applications must run as clients, connecting in to the qmgr on the MQ Appliance.
You might need to change the way they connect, if they are currently running on the same machine connecting over server bindings.
Other than that, the same app code should be able to run.
I am not sure where MQ Light APIs come into it, to be honest.

Hi MVic, thank you for reply.
We will not be having a separate server in future, the only box we will get is MQ Appliance box so if we can't run java application on that box, then probably we have to think some other ways.

Why? If your Java code 'manipulates' messages it's surely not going to do that to messages 'physically' on a queue? Does it not get the message, manipulate it, then put it back on the queue?
