What is JMS API
Elaborate the term JMS API?
Expert
A Java Message Service is a Java API that permits applications to create, receive, send, and read the messages. Planned by Sun and many partner companies, JMS API describes a common set of interfaces and related semantics that allow programs written in Java language to communicate with the other messaging implementations.The JMS API minimizes set of ideas a programmer need to learn use of messaging products but provides sufficient features to support sophisticated messaging applications. It also struggles to maximize portability of the JMS applications across JMS providers in same messaging domain.
The JMS API allows communication that is not only loosely coupled but also
-> Asynchronous: A JMS provider may deliver messages to a client like they arrive; a client doesn’t have to demand messages in order to receive them.
-> Reliable: JMS API can make sure that a message is delivered only once. Lower levels of reliability are obtainable for applications which can afford to miss messages or to receive duplicate messages.
The JMS Description was first published in August 1998. The new version of JMS Specification is Version 1.1 that was released in April 2002. We can download copy of the Specification from JMS Web site, http://java.sun.com/products/jms/.
