Hi, My requirement is as follows, fyi, I am using Weblogic 8.1 sp5: I have configured my weblogic with the connection factory, queue and temporary queue. Then I wrote a client a class to put the message in the queue. I also wrote the class to receive the message from that queue. Now, if I want to know, whether my message has been successfully delivered or not? What modification do I need to in sender as well as in receiver class? Do I need to look about this in the server? Or need to write a new receiver class to retrieve the acknowledgement? Please suggest me, this is very urgent. Thanks and Regards, KB
