i just wanted know that where MDBs are used in real life ??
I know that it has to do with deciding synchronous & asynchronous communication ...........

but i could not really understand its real use and advantage in real life.

so can any one please answer following doubts regarding MDB?

1) Why to use MDB?
2) Where to use MDB?
3) what are advantages of using MDB?
4) where exactly MDBs are used in real life?
5) can any one give any simple small demo of proper use of MDB with code?

I will really appreciate if any one can give any simple MDB application demo with code .

Regards,
Dhiren




1) Why to use MDB? : It is scalable and powerful lightweight mechanism to message communication.
2) Where to use MDB? : when you want to communicate with two heterogeneous system.
3) what are advantages of using MDB? : asynchronous message communication with multithreaded/paralleism(Best of CPU utilisation)
4) where exactly MDBs are used in real life? : where required Old Native system with new system integration.
5) can any one give any simple small demo of proper use of MDB with code? : Check the net you will get lots of stuffs.
Hi Buddies,

Any one can explain the mechanism or architecture of Java Messaging Service in Clustered environments ?
1. I want to define a queue and a consumer application association to the queue and wants to make clustered, so it will be created across all Node i.e Node1,Node2.....Node.n.
2. If i want to fire a message. to queue through queue sender API, how it will work ? will the message. available for all queue(Physical) in all nodes across clustered or only one ?
3. How my consumer will work ? will all consumer will try to get/fetch message from queue or only one ?

Please...anyone can explain...???
