Ha ha... I think this is a kludge,

Using a SecurityManager is a kludge?

but ok, I have "read"... so help

me... I want to stop Tomcat calling System.Exit(1)... what do I need to do to the catalina.policy file to do this? I imagine that instead of the embedded app shutting down the user will now get a security exception, which to me is wrong... but hey, I'll try it.

The 'System.exit()' example is the usual one, as you will remember from when you read the documentation:

Imagine I make a library for you... and your user application
does something
wrong... and then my library calls System.Exit and shuts down
the JVM... how
you going to fix that with a security manager??

The security manager can prevent the call from succeeding.  Read, don't
just assume it can't work.
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#exit(int)
will give you hint on the fact that exit can be prevented by a security
manager, for example.
