How do I expose data in a JSON format through a web service using Java?

Question

Is there an easy way to return data to web service clients in JSON using java? I\'m fine with servlets, spring, etc.

Answer 1

Yup! Check out json-lib

Here is a simplified code snippet from my own code that send a set of my domain objects:

private String getJsonDocumenent(Object myObj) (
    String result = "oops";
    try {
        JSONArray jsonArray = JSONArray.fromObject(myObj);

        result = jsonArray.toString(2);  //indent = 2

    } catch (net.sf.json.JSONException je) {

        throw je;
    }
    return result;
}
