Videos

Video 4.1: Benefits and usage scenarios of asynchronous processing

In this video we are talking about the benefits and possible usage scenarios of asynchronous processing.

Video 4.2: Implementing asynchronous web services

In this video we are implementing simple asynchronous web services.

Method	URI	Status	Description
GET	/api/thread	200	Returns request and response threads name

In this video is showing how to use ManagedExecutorService and Server-side Callbacks to calculate Fibonacci numbers async.

Method	URI	Status	Description
GET	/api/fibonacci/{i}	200	Returns the Fibonacci for i

Video 4.4: Implementing asynchronous web service clients

In this video we are showing how to implement an async REST client.
