Discussion Board
Action class
An Action class acts as a bridge between user-invoked URI and a business method. It provides an interaction between the contents of an incoming HTTP request and the corresponding business logic that should be executed to process this request. RequestProcessor also known as the controller will select an appropriate Action for each request, create an instance, and call the execute method. Action class provides a thread-safe manner in which multiple requests can run and controller can share the same instance multiple times.
