title: Tomcat servlet acting strange with json object
body: <pre><code>protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
      response.setContentType("application/json");
      PrintWriter out = response.getWriter();
      Gson gson = new Gson();
      LocationTypes locTypes = new LocationTypes();
      String json = gson.toJson(locTypes);
  
      out.print(json);
      out.flush();
  }
  </code></pre>
  
  <p>If i take the above code, and System.out.println(json), it looks like this : </p>
  
  <pre><code>    {"locationTypes":["Hospital","Church","Restaurant","Bar","Other"]}
  </code></pre>
  
  <p>What i get in the browser, when pointing to the url for the servlet, i get this:</p>
