HTTP Status 500 - Servlet.init() for servlet jersey-serlvet threw exception?

Solution 1
That error means you are mixing Jersey 1.x and 2.x. Both are totally incompatible, make sure that all your dependencies are of the same version.
com.sun.jersey
is for Jersey 1.x. It should not be used.
org.glassfish.jersey
is Jersey 2.x and should be used whenever possible.
Solution 2
I see one issue in your code
@Path("/") <--- here
public class Cliente {
@GET
@Path("/cliente")
As per your code, the url to access getNome method would be
http://localhost:8080/FerpaWS/ws//cliente
But, you are accessing
http://localhost:8080/FerpaWS/ws/cliente
So, either you removed @Path("/") or name something @Path("/app"). So, finally url would be
http://localhost:8080/FerpaWS/ws/app/cliente
