Remove read data for authenticated user?
===

In DDS what my requirement is, I have many subscribers but the publisher is single. My subscriber reads the data from the DDS and checks the message is for that particular subscriber. If the checking success then only it takes the data and remove from DDS. The message must maintain in DDS until the authenticated subscriber takes it's data. How can i achieve this using DDS (in java environment)?? 
                 
                        Any comments will be appreciated.....
