  //Test addCourse method (JSON version) of CourseService 
  public static void testAddCourseJSON() { 
 
    //Create JAX-RS client 
    Client client = ClientBuilder.newClient(); 
 
    //Get WebTarget for a URL 
    WebTarget webTarget =  client.target("http://localhost:8600/CourseManagementREST/services/course/add"); 
 
    //Create JSON representation of Course, 
    //with course_name and credits fields. Instead of creating 
    //JSON manually, you could also use JAXB to create JSON from 
    //Java object. 
    String courseJSON = "{"course_name":"Course-4",  "credits":5}"; //Execute HTTP post method Response response = webTarget.request(). ...
