Uncaught initialization exception created by servlet, when executing a servlet on RAD

I'm trying to create a new servlet on my app. I'm developping on RAD on Websphere. The class is this one : 

import javax.ws.rs.*;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import framework.Log;



@Path("/checks")
public class Checks{


    private static final long serialVersionUID = -6790501052160536787L;

    private static final String NCC = Checks.class.getCanonicalName();



    @GET
    @Path("list")
    @Produces(MediaType.APPLICATION_JSON + ";charset=utf-8")
    public Response doGetListe() {

        Response.ResponseBuilder rb = Response.status(Response.Status.OK);
        rb.entity("[{ 'test' : ' test ' }]");
        return rb.build();


    }

}

I don't have much more details, so what i'd like to know is, where does this error come from? Or, how can i debug it? If i put breakpoints on my class, they are never triggered. The error must be before the class is executing. As i don't really know how all of this work, i'd like to have some tips to resolve this error.

EDIT :

Here are the logs :

First of all it is not a servlet but JAX-RS resource. Second remove jersey dependencies from your pom and use javaee dependency with the scope provided (you may need to adjust version depending on which WAS/Liberty version you are running), as WebSphere provides JAX-RS compatible runtime and you need to include that in your application.

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>7.0</version>
        <scope>provided</scope>
    </dependency>

Error you see is related to jersey/xml libraries that you have in your WEB-INF/lib. Remove all libraries form there that are not yours.
