Mobile messaging applications have proven extremely successful in the consumer world to support flexible person-to-person communications. However, messaging is much more than interperson communications. The wide use of messaging-oriented middleware (MOM), such as the Java Messaging Service (JMS), has made messaging one of the most important person-to-machine or machine-to-machine integration schemes in modern enterprise applications. Compared with tightly integrated applications, messaging-based solutions are more reliable, flexible, and scalable. Those are critical advantages in the mobile enterprise world. Using iBus//Mobile and IBM WebSphere MQ Everyplace as examples, we discuss design principles of mobile MOM applications. We also walk through sample code for simple applications using both systems.
