title: How to consume 3party json services in GWT
body: <p>I'm looking for the best way in GWT to access a 3party json rest service and parse its response quickly. The rest service offers the <code>callback</code> parameter, and the example they gave us is using jQuery.jsonp:</p>
  
  <pre><code>$.ajax({
    type: 'GET',
    url: 'http://server_name?id=and_id&amp;callback=?',
    contentType: "application/json",
    dataType: 'jsonp',
    success: function(js) {/*{id='id',status='sold',prod_name='name',price=0.0 ...}*/},
    error: function(e) {}
  });
  </code></pre>
