Hi
This is essentially what is happening. It is called once from a simple CL program using the 'Java' command, and runs all day communicating via data queues with RPG programs.
I just don't understand why the AS400 is so slow to startup, when a PC can do it in a fraction of the time.
Thanks
Duncan

How is it being loaded? Invoked by a user? Called from RPG? Called from Java?
My recommendation would be to engineer the application to run as a server and take requests, and send results, via a data queue.
Then the Java code is running all the time and can be activated by anything that can send a data queue entry.
You will experience the startup penalty once and then the code is active.
