Call a web service in java application from main method

I am using Tom Cat server and Jersey Framework to implement a RESTful web service. I have a main method, and I want to call this in main, and run the Tomcat. How can I do that?

@GET
    @Path("/{parameterPk}/{parameterData}")
    public Response getJSONObj(@PathParam("parameterPk") String parameterPk,

            @PathParam("parameterData") String parameterData) {
        System.out.println("Starting...");

        JSONObject jsonObj = new JSONObject();
        jsonObj.put(IDENTIFIER_JSON_ID, parameterPk);
        jsonObj.put(IDENTIFIER_JSON_DATA, parameterData);

        JSONArray jsonarray = new JSONArray();
        jsonarray.add(jsonObj);
        System.out.println(jsonarray);

        JSONObject jsonMain = new JSONObject();
        jsonMain.put("Employee", jsonarray);
        System.out.println(jsonMain.toString());

        return Response.status(200).entity(jsonMain.toString()).build();
    }
