Difficulty getting started

[klclee]

Hi i am trying to run my first web project. I cloned the project's master followed the instructions on how to write a web app. When I run the app: http://localhost:8080/myapp I get the following error:

javax.servlet.ServletException: Filter execution threw an exception
