JMS to Excess

The Java Message Services (JMS) API attempts to provide an

infrastructure where an enterprise computing infrastructure's elements

can exchange information with one another. That information may include

requests for values or services, responses to requests, and event

notifications.

The JMS architecture is particularly adept at exchanging messages

asynchronously; its facilities allow for slow, and perhaps

intermittent, connectivity between clients. For that reason, the JMS

API particularly interests application developers for mobile devices --

PDAs, mobile phones, etc
