Anil,

Welcome to JavaRanch

can any one please help me in understanding the differences between JMS and MDB


JMS is a specification. Message Driven Beans (MDB) is a type of EJB which are invoked based on JMS events. MDBs are used for asynchronous processing.

Ex: In JMS, you can have a "queue" to which messages can be delivered. This queue can be listened by a MDB. Whenever a message is delivered to the queue, the JMS server will invoke the onMessage method of the MDB and deliver it the message.
 
Don't get me started about those stupid light bulbs.
