A client asked my about issues related to setting up SSL and ActiveMQ and my immediate response was that there should be no problem. Indeed, I found several posts (wiki.ndgf.org/display/ndgfwiki/Standalone+Apache+ActiveMQ+with+SSL+support),listing the steps needed to setup up such a system.

Afterwards in the process of researching, I found that there are new protocols (st least for me) named STOPM (stomp.codehaus.org/) and AMQP (Advanced Message Queue Protocol ) supported only by several vendors but are the standard these days.

In one of my previous posts I mentioned Lshift (www.lshift.net/blog/), the company that developed RabbitMQ, which was written in Erlang and is supposed to be an extremely fast MQ server.
