Is it possible to send/receive JMS messages from a Progress V10 (specifically: 10.2B06) ABL application or is it working exclusively with Sonic?
If the answer is yes, pointers to documentation would be much appreciated.
Yes, you just have to find a JMS that supports the STOMP protocol (like RabbitMQ or ActiveMQ), then you implement the STOMP protocol in pure ABL. It isn't a very complicated protocol so there are several ABL solutions out there (I even wrote one back in the day), but I think the most popular and well-maintained is probably this one by Julian Lyndon Smith so if I were you I'd go with that one.
