This page shows how to handle JSON data returned from the server.

The form below submits a message to the server and the server
echos it back in JSON format.

<form id="jsonForm" action="json-echo.jsp" method="post"><div>
Message: <input type="text" name="message" value="Hello JSON" />
<input type="submit" value="Echo as JSON" />
<br />

out.print("{ \"message\": \"" + request.getParameter("message") + "\" }");
