I have used User Queues. I wrote a service program that does the
create, delete, read and write and have written to them with C. RPG is
very easy to interface. C is a mother of all mothers. The Java stuff
just allows you to use them in Java.

Main reason for using them is speed. They are faster than data queues.
My test said about 40%. The User Queue service program is available is
anyone wants the code.

I would like to write a java program that would run on os400 and
would extract some messages from a user queue, process them, and
dumps them back into another user queue.

1. Create/open new/existing user queue

2. Read the user queue content one by one - if the queue is
not empty; if empty, block until it becomes non-empty, again

3. Write messages to the user queue.

I'm not too familiar with using User Queue's ... but what you describe
sounds like a perfect use for a data queue.

One thing I noticed about a UserQueue is that it uses native methods ...
so you can only run java code using a UserQueue on the i.
