Need Help with SecurityManager

[Brad Rhoads <br...@zethcon.com>]

First, is there a good tutorial on using SecurityManager? The info in the
Tomcat Docs is rather sparse. Ultimately what I'm looking to do is protect
non-jsp files, such as PDF docs.

But so for I can't even start my app with the SecurityManager turned on.
Here's what I get:

catalina.out:

Starting service Tomcat-Standalone
Apache Tomcat/4.0.1
Template Servlet Error Loading Screen Definitions: URL
/WEB-INF/screendefinition
s_en_US.xml not found
Starting service Tomcat-Apache
Apache Tomcat/4.0.1

I'm not sure why the .xml file isn't being found, but it doesn't cause a
problem with the app - everything works fine w/o SecurityManager.
