You'll need to write native code for this, because its OS dependent.

You can handle OS signals in the shell script ("trap") and communicate them in some "pure java" way to the Java process.

Hi,

the following trick might only work with some versions of Sun JDKs and is not recommended, however:

There is a class called sun.misc.Signal and an interface sun.misc.SignalHandler which does, what you need. But use it with care! The VM uses its own signal handlers and might interfere with yours. There is an option to the VM "-Xrs" which influences how the VM handles signals and which signals it handles by itself.

I have written a signal handler that works fine.However you shoudl note that java uses USRSIG2 and other signals for its own purposes. You cannot override some of these without upsetting the JVM.
