title: Unable to consume RestFul web service using jersey client
body: <p>My service side code is implemented using Resteasy</p>
  
  <pre><code>@GET
  @Path("/ad-details/{query}")
  @Produces("application/json")
  public String getAdDetails(@PathParam("query") String id)
  {
      //Validator v =  ESAPI.encoder().encodeForHTML(id);
      //String id1 = ;
      //System.out.println(ESAPI.encoder().encodeForHTML(ESAPI.encoder().canonicalize(id1)));
      String adDetailsResult = "";
       System.out.println("reached Service");
      AdServiceProvider ad = new AdServiceProviderImpl();
      AdDetails details = ad.getAdDetailsById(Long.parseLong(id.trim()));
      adDetailsResult = gson.toJson(details);
      //System.out.println(adDetailsResult);
      //adDetailsResult = ESAPI.encoder().encodeForHTML(ESAPI.encoder().canonicalize(adDetailsResult));
      System.out.println(adDetailsResult);
      return adDetailsResult;
  
  
  }
  </code></pre>
  
  <p>and my client side code consuming this service is using jersey api 
  and the code is as mentioned below.</p>
  
  <pre><code>protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
      // TODO Auto-generated method stub
      System.out.println("reached servlet");
      response.setContentType("application/json");
      String adId = request.getParameter("adId");
      System.out.println(adId);
      Client client = Client.create();
      WebResource wr = client.resource("http://localhost:8080/com.pandora.services/service");
      String adDetailsResult = wr.path("ad-details").path(adId).get(String.class);
  
      PrintWriter out = response.getWriter();
      out.print(adDetailsResult);
  }'`
  </code></pre>
  
  <p>however when i make a call i am getting the following error</p>
