Question on use of JMS

Question

I am new to JMS and I have a question on applicability of JMS.
I have gone through different resources which explains the applicability of JMS. I was wondering if I can use JMS for this purpose:
When the user (end-user) initiates a business transaction (a business component in a system which needs a long while to process), it (the process) should run in the background while the user should be able to perform other tasks on the system.
Other way of saying is to incorporate "asynchronous" behavior to that particular component.
An example of such context is: In a text editor (say JBuilder), user can activate the search, and the user can do other things (say open/close/edit a file) simultaneously while the search process runs background until its done.
Can I know if its wise using JMS ONLY for this purpose. I guess other option for this purpose is to use Multithreading.
Any suggestions is appreciated.
Thanx.
Pramodh.

Answer 1

You can use it in the context of mutithreading but it means JMS is not meant for Multithreading. Its basically meant for object communication.
It will be useful when you are writing some event based applications like Chat Server which needs a publish kind of event mechanism to send messages between the server to the clients who got connected with the server.
Moreover JMS gives Loosely-coupled kind of mechanism when compared with RMI which is tightly-coupled. In JMS there is no need for the destination object to be available online while sending a message from the client to the server. But in RMI it is necessary. So we can use JMS in place of RMI where we need to have loosely-coupled mechanism.
I hope this will give you a good idea about JMS.
