I have downloaded the bundle of jboss-5.0.1.GA and configured the JBoss_Home and Path. Server is running fine. I have gone through the document you have mentioned and confused in JBossMQ(4.2) to JBoss Messaging-Chapter-4(http://www.jboss.org/file-access/default/members/jbos.... Is it necessary to use/configure database? In my case there no need to use database. Why we need to configure ServerPeer? My requirement is very simple. I want to use Jboss Messaging for a Queue only. i.e. I want to configure/create a Queue, which would store a set of object so that client can lookup those object. Form which chapter / from where I need to follow the document? Details about my application: ----------------------------------- It is a client side application, a server is invoking my application and sending an Object. - Object contains a set of objects/values. I need to persist in database. - I am persisting it into database. Depends on values and size of object it takes time in persisting it. Sometimes while persisting server sends another object and because of this synchronization/transaction is not maintained, you may suggest me that i should implement thread safety/Synchronized in my code, but in this case i will loose the Object which is coming from the server. I planned that if i can save object in JMS Queue and then process it from there; then it would help me to accomplish it. Your suggestions would be a good help. Arun.
