Q:

404 page when run as web application project

I want to create a basic Google Web Application project and i get an 404 Page not found error. 
I followed several tutorials and what i do is this: 
Open eclipse - File - New - Other - Web Application Project (under Google) - name it - (it doesn't matter if i check "Use GWT" or not the result is the same - Finish.
Right now i have a newly created web application project, so i can test it in localhost. I right click it, run as - web application project (with google icon). After it finishes in my console i have this:

Mar 22, 2017 10:13:58 AM com.google.apphosting.utils.jetty.JettyLogger info

  INFO: Dev App Server is now running

I open Chrome and go to localhost and i get:

HTTP ERROR: 404
Problem accessing /. 
  Reason:
  NOT_FOUND
Powered by Jetty://

I must specify that i am deploying behind a proxy server. I tried also to run it without proxy, same result. All my settings are correct, because if i create a Dynamic Web Project and i deploy it on a Tomcat server, that one works fine. 

A:

The solution that worked for me is this. Check your Java facet. It has to be 1.7. Mine was 1.8.
Thank you.
