Question

b) What is JMS? How Message Driven Bean (MDB) is useful in application integration

Answer 1

Answer:

The Jakarta Messaging API is a Java application programming interface for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem, that can be used to facilitate the sending and receiving of messages between software systems.

Developers of JMS messaging applications should, therefore, limit JMS client components that run in a Sun Java System Application Server environment to JMS 1.02b. For more information, see the Sun Java System Message Queue Developer’s Guide or Release Notes.
