Enter ... Java MessagingEnter ... Java Messaging

Service allowing Java-based applications to communicate

Two models:– Publish and Subscribe (1Many)

Messages passed between publishers and subscribers via topics

– Point-to-Point (11) Messages passed between senders and

receivers via queues


Java Messaging Service (JMS)The Only Industry Standard for MessagingJava Messaging Service (JMS)The Only Industry Standard for Messaging

Developed and maintained by Javasoft– Standardized since 1998

A way for Java programs to interact Embraced within J2EE specification An API and set of semantics A common programming framework for:

– Point-to-Point (PTP)

– Publish & Subscribe (Pub/Sub)
