how to access json data mule esb

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 :

{"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]}

I want to access to_user attribute from this json format. I have tried using #[json:to_user] but it simply prints it as a string and doesnt return any value. Please help. Thanks in advance.

JsonPath expression are depreciated for now and you will even not get enough document on it for doing ..
So, currently you need to use either :- <json:json-to-object-transformer returnClass="java.lang.Object" doc:name="JSON to Object" />
or <json:json-to-object-transformer returnClass="java.util.HashMap" doc:name="JSON to Object" />
or even <json:json-to-object-transformer returnClass="java.util.List" doc:name="JSON to Object" /> to extract data from JSON depending on the JSON data

The right expression based on your sample JSON is:

#[json:data[0]/to_user]
