33 * Asynchronous Workflow processing using JAX RS RESTeasy implementation
34 * Both Synchronous and Asynchronous BPMN process can benefit from this implementation since the workflow gets executed in the background
35 * and the server thread is freed up, server scales better to process more incoming requests
37 * Usage: For synchronous process, when you are ready to send the response invoke the callback to write the response
38 * For asynchronous process - the activity may send a acknowledgement response and then proceed further on executing the process
