Advanced Queuing -- LISTEN

Hi,
 Does any body got the working code for advance queuing listen process. i.e i wrote the application by using advance queue. When i execute the pl/sql block on dequeued end it listen for the message, but as soon as it received the message, it dequeue's the message and closing the application with message PL/SQL executed succefulley on "SQL>" prompt.  My requirement is, it should listen for the messages. Like daemon's in UNIX.

Thanks
