I haven't done it but I would test this:
Make a lifecycle module ,by doing this
class myclass implements com.sun.appserv.server.LifecycleListener
{
public void handleEvent(){ /*make your code here*/}
}
When you get an INIT_EVENT you can then call your code that makes a socket
bind to a port that listens for incoming connections(binary messages
etc).You can put your code in a .jar and place it somewhere like
<glassfish_root_directory/lib> where glassfish classloaders can find it.
When you get an SHUTDOWN_EVENT you can then close the socket and release the
resources of your program.
