I am using message driven bean and Foreign JMS server to publish messages..When I am submtting a form ,some parameters from that form should be sent to QUEUE.Here publishing works always.But subscription by Message Driven Bean works sometimes and sometimes not.what might be the reason?

One reason could be for the same queue there might be some other consumers also. Make sure that only your MDB is receiving message from the queue.
Thanks,
