Check all the Jars are properly Configured or not. Clean the Eclipse server. Clean Tomcat Working Directory. Go to Menu Project -> Clean. Restart the server and Application.

If you have configured and built project properly with all required jars and still getting same error then you might missed to create classes folder. If we are using existing project setup and configuring it, then default output folder should be entered manually as per project requirement. In my case, eclipse was giving default output folder to /bin but it was configured to project_name/WEB-INF/classes. So I have changed it to project_name/WEB-INF/classes

The Tomcat Servlet API jar is available here.
