For those who don't know the JMS acronym, it stands for Java Message Service and it is a well-known set of APIs used in Java-based environments to provide publish/subscribe and message queuing paradigms. Not only does the JMS Extender provide that same set of APIs as a JavaScript client library (and other languages in the future), but it also extends the reachability and scalability of a JMS broker (typically a local-area-network component) to the entire Web.
