Eclipse Tomcat SEVERE: Error loading WebappClassLoader

Tomcat starts on Eclipse successfully, however any action involving the Servlet gives the error below.

I suspect the problem is that TomCat is looking in the WEB-INF folder for classes, though I have no idea where Eclipse has compiled and hidden them (not there for sure). How do I fix?

SEVERE: Error loading WebappClassLoader
  context: /MyEclipseProject
  delegate: false
  repositories:
    /WEB-INF/classes/

  • Clean your project
  • Refresh it
  • redeploy it

I tried these steps and my app works :)

The compiled class files are under $user.dir/webContent/WEB_INF/classes folder. If there are no classes there, I suggest you remove the project from the tomcat server, then clean your current project. Finally, run your porject(jsp etc) on the server again. I hope this will help.

Please remove the tomcat server runtime library from your project build path and then add the tomcat server again. Run now, it should solve your problem I guess.
