Errors after adding Servlet

Hello All,

I tried to create a google app engine project in IntelliJ 13 trial version. But the project failed to run after adding a servlet. If I remove the servlet and use only jsp, then everything is working fine.

Any one had expericed this before?

Here is the errors after adding servlet.....

Using javac 1.7.0_25 to compile java sources

Compilation completed with 3 errors and 0 warnings in 4 sec
