Get JSON Details from the Last Operation

See more MIME Examples

Demonstrates GetLastJsonData, which copies structured details from the most recent operation into a JsonObject when such details are available. Many operations produce no JSON data, in which case the object is empty or minimal.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Tip: Code to parse the returned JSON can be generated with Chilkat's online tool at https://tools.chilkat.io/jsonParse.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
