Re: Using JAVA for core business logic - Good/Bad?

I am looking for opinions/reasons, with supporting information, on the use of JAVA to write business logic instead of RPG on the iSeries. The impetus for this request is that our architecture group is suggesting that we write any new business logic in JAVA for portability reasons. Keep our current application code in RPG, just the new stuff. That's what I have been able to ascertain to this point. I know it's not much. The general corporate direction is to move to an SOA architecture with and enterprise service bus (?) handling the service calls between applications.

Hi Rick!

There are lots of opinions on this list, so be prepared to get varying views <grin>.

At the same time, I'd suggest moving your question to the JAVA400-L mailing list. It's really much more tailored to talking about Java on and around the i platform. And in the interest of full disclosure I moderate that list and in my opinion, Java is best for middleware while I prefer RPG for business logic. But we can discuss the technical and business merits in detail on the Java400 list.

I don't know if David agrees - let's let him weigh in on the topic.
