Welcome to the JavaRanch, Sanjay!

We have a forum dedicated specifically to Tomcat, so I'm going to move this thread over there so that the Tomcat experts can see it.

Most likely one of 2 things is at fault. Either you have a bug in the web application or your copy of Tomcat is corrupt. And since I don't see a message saying that any webapps have started to deploy, I'm thinking it's a problem with Tomcat.

Since you're running Tomcat within the Eclipse IDE, there's actually a third possibility, which is that Tomcat itself isn't corrupt, but the Eclipse IDE's handling of Tomcat is corrupt. I have many complaints about the WTP server plugin that comes with Eclipse. In fact, I hate it so much I ignore it and run using an independent Tomcat management plugin (sysdeo/mongrel).

The way to check if it's the IDE's fault is to attempt to launch Tomcat stand-alone and see if you still get that error. If you do, re-install Tomcat. If you don't, you're going to have to "persuade" the Eclipse WTP to clean up or do like I do and install Mongrel.
