Solution 1

I faced this issue when required jars were missing. Please recheck whether your dependencies are getting bundled properly. If not, try to look in eclipse logfile for more information.

Solution 2

I got a similar exception when my web.xml file couldn't find my servlet. I had changed the package name the servlet was in and the web.xml file wasn't updated.
