The servlet name is na. URLs will follow the form:
http://www.example.com/naWhen using HTTP GET, you encode JSON into the URL using the query parameter json. For example
http://www.example.com/na?json={}When using HTTP POST, the body of the HTTP message is the JSON message. The ContentType for the JSON messages should be text/plain so that when you are debugging, the browser will not try to use an external process for viewing the json content.
