The jsonpstreaming Example Application

This section describes how to build and run the jsonpstreaming example application. This example is a web application that demonstrates how to create JSON data from form data, how to parse JSON data, and how to write JSON output using the streaming API.

The jsonpstreaming example application is in the tut-install`/examples/web/jsonp/jsonpstreaming` directory.

The following topics are addressed here:

Components of the jsonpstreaming Example Application

The jsonpstreaming example application contains the following files.
