Detecting client disconnects

knuffelbert Jan 13, 2007 7:27 AM

Hello there,

Just a quick question, hopefully a quick answer too :)

Normally the client application will call the ejbremove method on the stateful session bean running within JBoss 4.0.something . However cases where the app crashes or the internet goes down have to be caught as well. Is there any way to let the ejbremove method be called automatically (preffered) or to get a notification of some sort?

Thanks in advance!

Tom

A "no, can't be done" is also an acceptable answer :) Does really noone know this?

no, at least not without some custom plumbing. The bean is removed either on a client request or on a connection timeout.

You could code some sort of keepalive service that polls a client for a connection regularly.
But that would require a custom client library as well which would respond to that polling.
