title: how to access json data mule esb
body: <p>i want to access json data generated from the sync flow into an async flow.
  I am getting json data from sync flow correctly and i want to fetch certain attribute value from that my json data is as follows :</p>
  
  <pre><code>{"data" : [{"in_timestamp":"2012-12-04","message":"hello","out_timestamp":null,"from_user":"user2","ID":43,"to_user":"user1"}]} and to user is #[json:to_user]}
  </code></pre>
  
  <p>I want to access to_user attribute from this json format.
  I have tried using <code>#[json:to_user]</code> but it simply prints it as a string and doesnt return any value.
  Please help. Thanks in advance.</p>
