Bhargavi, I edited your post and its title to remove all the "Urgent" claims. Please read this to see why.

Yuck. I hate debugging digester problems.

First, check to see if you have a valid server.xml file. Secondly, you might want to temporarily remove all your webapps, in case one of them has a bad web.xml - although normally that should only affect the badd app and not Tomcat itself.

If that didn't help, go to your JAVA_HOME/jre/lib directory and edit your logging.xml file. If you don't find it there, nose around the JRE directories. It's there somewhere.

In logging.xml, add an entry for org.apache.commons.digester to set the digester's logging level to something like FINER. Make sure that your primary logging output is set to print messages of this level or higher.

Restart Tomcat. Somewhere in all the glop that comes out from the Tomcat logs you may be lucky enough to see exactly what it was attempting to do when the exception ocurred.

Actually, I see that your stack trace is specifically complaining about server.xml, so before you start cranking up the logging level, you should verify the TOMCAT knows where the server.xml file actually is. If you're using the sysdeo Tomcat plugin, that's done by telling the Window/Preferences->Tomcat dialog what your CATALINA_HOME and CATALINA_BASE directories are.
 
I agree. Here's the link: http://aspose.com/file-tools
