Example code files under "Anatomy of a Web App" don't run

[qianzhong516]

Hi, by following the tutorial Anatomy of a Web App, I have set up the exact same directory shown in the image below: but accessing localhost:8080/HelloWorld/hello returns not-found error.

I've also tried downloading your code from here and copy-pasted it under my webapps directory, it didn't work either.

Please advise how to fix the issue, thanks :)
