When I start Tomcat I get the following error:
Jun 10, 2010 5:17:25 PM org.apache.catalina.core.StandardContext start
SEVERE: Error filterStart

I too got the same error and struggled a lot in fixing this issue. Spent quiet a bit time in searching Google and found the following solution and my issue got resolved.
the issue was due to, missing Struts2 Libraries in the deployment path. Most of the folks may put the libraries for compilation and tend to forget to attach required libraries for run-time. So I added the same libraries in the web deployment assembly, and the issue was OFF.
