I’m new to Jetty, I tried to run the sample program here “http://www.codeproject.com/Articles/128145/Run-Jetty-Web-Server-Within-Your-Application”
but I got error message on my page “http://localhost:8585/runJetty/“
"HTTP ERROR: 503
Problem accessing /runJetty/. Reason:
Service Unavailable

Actually, I solved the problem. I run it by eclipse jetty plugin.
I didn’t have the JDK lib in my eclipse, that’s why the message keep showing that I need the full JDK installed, that’s the main reason.
I installed two versions of jetty plugin, wich is jetty7 and jetty8. I think they conflict with each other or something, so I removed the jetty7, and it works!
