Java EE (Java Enterprise Edition) General Discussion

I don't understand why I am getting this error in my Tomcat catalina log:

May 17, 2005 9:39:45 PM org.apache.tomcat.util.digester.Digester fatalError
May 17, 2005 9:39:45 PM org.apache.tomcat.util.digester.Digester fatalError

I am developing on a Windows XP machine with jdk 5.0 and Tomcat 5.5.9. I went back and discovered that I was missing my filter-mapping element, however, that didn't change the error I was receiving. Here is my web.xml:

Here is my corresponding security-config.xml:

If someone could shed some light on this I'd really appreciate it.
