The Java Message Service (JMS) provides a way for the components of a distributed application to talk asynchronously, or for welding together legacy enterprise systems. Think of it as application-to-application e-mail. Unlike COM, JMS uses one or more JMS servers to handle the messages on a store-and-forward basis, so that the loss of one or more components doesn't bring the whole distributed application to a halt. JMS consists of a set of messaging APIs that enable two types of messaging, publish-and-subscribe (one-to-many) and point-to-point (one-to-one). The highly lucid explanation of the ways in which these work makes the technical content a lot more approachable. In practice, however, Java Message Service is still a book for Java programmers who have some business programming experience.
