Hi Neha,
You are using @PathParam incorrectly. This annotation is utilized to
extract information out from the request URI path component and not
information sent in the POST request body (namely the JSON content).
@QueryParam is used to extract information out from the query
parameters of the request URI query component.
The following overview document helps explain things in more detail:
http://wikis.sun.com/display/Jersey/Overview+of+JAX-RS+1.0+Features
Do this instead:
@POST
@Consumes("application/json")
@Produces("application/json")
public String setUserStatus(JSONObject in) {
...
}
Paul.
