Not very secure, is it? Not reading documentation, aren't you? See Security Mgr how-to in Tomcat documentation; it starts by discussing possibility of someone having System.exit(1) in code that's running within the servlet container. -- Wolf a.k.a.

Not very secure, is it? luca Why does that make it insecure? A terminated application is very secure ;-) Tomcat runs in the JVM, if you exit the JVM with System.exit() then Tomcat terminates. It's a silly thing to do, so don't do it. -- Nigel Wade, System Administrator, Space Plasma Physics Group, University of Leicester, Leicester, LE1 7RH, UK E-mail : [email]nmw (AT) ion (DOT) le.ac.uk[/email] Phone : +44 (0)116 2523548, Fax : +44 (0)116 2523555 Back to top William Brogden Guest Posted: Tue May 25, 2004 1:06 pm    Post subject: Re: System.exit(0) and tomcat On Tue, 11 May 2004 09:34:56 GMT, luca <luca_remove (AT) tin (DOT) it> wrote: Quote: Hallo, I just noticed that using System.exit(0) in my app has the nice effect of stopping tomcat 4!!!

Start your tomcat with the -security switch and it will use catalina.policy file to configure a SecurityManger this allows you to proscribe in minute detail just what each application is allowed to do.
