JSON Mapping Sample

About the sample

A popular data format used with RESTful services is JSON. This sample contains a data service with JSON output mapping templates. Go to JSON Mapping for details on how to use JSON templates for output mapping in data service.

Building the sample

The sample data service JSONSample should be deployed using the instructions in Samples Setup.

Running the sample

The sample service can be run using any client that can do REST calls. For example, use tools such as cURL or Advanced REST Client Chrome browser extension. The HTTP header "Accept" should be set to "application/json" and also, if a JSON payload is sent to the server, the HTTP header "Content-Type" should be set to "application/json".
