title: Convert from LinkedHashMap to Json String
body: <p>I'm Workin with Mongo using Jongo, when I do a query I receive a <code>LinkedHashMap</code> as result.</p>
  
  <pre><code>Iterator one = (Iterator) friends.find(query).projection("{_id:0}").as(Object.class);
  while (one.hasNext()) {
      LinkedHashMap data = new LinkedHashMap();
      data = (LinkedHashMap) one.next();
      String content = data.toString();
  }
  </code></pre>
  
  <p>the problem is that  if the json is <code>{"user":"something"}</code> content will be <code>{user=something}</code>, it is not a <code>json</code> is only <code>toString</code> method from <code>HashMap</code>.</p>
  
  <p>How I can get the original <code>JSON</code>?</p>
  
  <p>I don't have a <code>class</code> to map the <code>response</code> and it isn't a solution create a <code>map</code> class, that is why I use a <code>Object.class.</code></p>
