Answer
I know this thread is a year old now but having experienced the same problem I managed to solve the problem by setting a target server for my project.
i.e. right-click on your project and select 'Properties' -> 'Targeted Runtimes' and select the server you going to run your web app on (Tomcat 6 or 7).
