I'm having some difficulties with ActiveMQ. I have a legacy ActiveMQ server set up using version 5.5. I also have a newer messaging consumer running with version 5.8 that needs to consume messages from the legacy server. When I try to create a queue within the legacy server, I get no error messages, but no queue gets created either. I thought maybe there are some JMS options that are not supported with the older server, but I boiled down the JMS options to just the 'timeout=x' with no luck.
Is there any reason ActiveMQ 5.5 can not interact with 5.8?
No - there is no particular reason an ActiveMQ v5.5 server cannot interact with a v5.8 client. Of course it is an untested scenario and you'd forego bug fixes and new features but it should work. Always upgrade if you can. :)
