Catching System.exit() or How to avoid System.exit() - Third Party Tool ???

Question

Hi All,
I am using a third party tool which is internally calling System.exit sometimes and my application
got terminated most of the times.
It is happening always when i call a particular method of that third party tool.
Is there any way to catch or avoid the System.exit while using the particular method?
I need this urgently...Please kindly help.....
Thanks,
J.Kathir

There's a fair bit to it, and you should refer to the appropriate java Tutorials. Bascially you create a .policy file and install a sercurity manager with:
System.setSecurityManger(new SecurityManager());The policy file grants a set of permissions to various "code sources", basically each codesource is a classpath entry. You could grant "AllPermissions" to your own code, and a more restricted set of permissions to the application you're running. But you can't subtract permissions, i.e. you can't say "this code can do anything except call System.exit().
I doubt this is going to provide you with a good solution. It's tiresome to set up, and when the client app called System.exit it would crash, which might not result in a clean status.
I'd consider if you should be using this client app in the same JVM, rather than creating a subordinate JVM using Runtime.exec.
