Detect if JAR has loaded at runtime

[casadelnorte]

We have a very odd need to detect - at runtime - if a JAR has been deployed in a JBoss instance, so that we can do some special handling. Don't ask.

However - does anyone know "the best" method do detect if a JAR has been loaded?

I've tried several methods - and checking for <jboss-install>/server/default/lib/ works but it can't be the best way. It feels like a total kludge.

The need, coded, will look something like:
if (jarHasBeenLoaded) doSomethingSpecial();

So - all you hotshot Java folks out there! Any advice? [[be nice]]

Thanks!

How about using Class.forName("xxx") where xxx is the full package name of a class found in that jar file.

Peter - THANK YOU. That is of course the right way to do it. And it works fine.

Thank you!
