I am trying to create a web application with a display that updates based on messages on an Enterprise Service Bus (specifically, running on JBoss EAP 5). At present, we have a cache service sitting on the ESB, and the web application polls the service periodically to update its display. I would like instead for the cache service to be able to push data to the web application whenever its cache is updated (i.e. make the web application's update be based on the receipt of a message, rather than on a timer).
Does anybody know of any libraries (or other design patterns that I haven't thought of) that could be leveraged to help implement this functionality?
