RE: Communicating between java & rpg?

Title: RE: Communicating between java & rpg?

We use MQSeries and XML to enable communication between Java and RPG in a given application.

I don't think that this is less work than data queues, since you have to write
listeners, data exchange protocol, a framework to handle the queries. Should be
the same work, but with another technology (MQ instead of data queues).

In a recent redbook about java and iseries, there is several chapter about java
interoperability on the as400.

My suggestion would be: don't use something specific to the AS400. So, as Even said,
MQ would be preferable.

Given that the processes will be on separate systems have you thought about
MQ ? What you are describing sounds like a good scenario for MQ rather than
trying to deal with all the process etc issues yourself.
