Empty answer when trying to get JSON from Jersey Server

I try to build a RESTfull webservice.
On the backend I use a Jersey Server. On the Frontend I want to get the data with jQuery using ajax methods.
I took the example from http-://www.mkyong-com/webservices/jax-rs/json-example-with-jersey-jackson/ and tried to get the Data with $.getJSON and $.GET.

The problem is, that I always can't access the response data. Also jQuery always only executes the fail method.
After that I tried it with a simple servlet. With that I get the same result.

Does somebody know what I am doing wrong or how I can make this stuff working?

The project is deployed on a Tomcat 7.
