To run Tomcat with a security manager, you must add your own policy lines to the catalina.policy file—like when you build a SecurityManager.

The catalina.policy file can be found here:

<TOMCAT INSTALL>\Apache Group\Tomcat 4.1\conf\

After you modify this file, run Tomcat from the comand prompt like this:

<TOMCAT INTALL>\Apache Group\Tomcat 4.1\bin>catalina start -security

Please note that, if you run Tomcat without the -security option, your modifications will have no effect.
