Jetty shows http error message 503 SERVICE_UNAVAIL

问题:

I developed a maven module application that works fine using (google appengine; maven; springmvc).

3 weeks after when I decided to add some features I noticed that I can no longer deploy it on the local, when I try to do so, I get:

HTTP ERROR: 503

Problem accessing /. Reason:

SERVICE_UNAVAILABLE Powered by Jetty://

NB : I did not change the code(so I'm pretty sure that it's not a source code problem), I just installed some applications like jenkins and sonar.

the solution is nick's comment:

This happens usually when one of your servlet mappings is broken. You should double-triple-check your web.xml.
