Writing to JMS queues from RPG programs

[svdv <Sr...@Copart.Com>]

Hello All,
   We are looking at using ActiveMQ as a way to have asynchronous delivery
of data from a AS/400 backend to a front end Java application. There is a
always IBM's Dataqueues that can be used. But having a JMS based interface
to communicate between the front end and the back end would provide a better
architecture. Could someone please shed some light if this is possible with
ActiveMQ

Thanks in Advance
Sriram

Take a look at the STOMP protocol:

http://activemq.apache.org/stomp.html

The STOMP protocol is used to implement clients for all the scripting
languages because it's a very text-only protocol. Maybe you could
create a STOMP client for RPG.

Another alternative is to use Java from the AS/400 so that you could
just write an application that makes standard JMS calls to the
ActiveMQ broker.

Have you looked at HTTPAPI by Scott Klement ?

Thank you for your response. I am in the process of exploring the REST based
approach as RPG has a way to send HTTP POST requests. Currently RPG does a
HTTP POST to a servlet which processes the information synchronously. By
using REST based service and hooking it up to a ActiveMQ queue i can have
the RPG calls processed asynchronously.

Thanks
Sriram

Hello Sriram

If there is a HTTP package for RPG then the application could use the REST
protocol which seems to be very easy to implement. (However I have only
experience with STOMP.)
