Application presentation layer

The application presentation layer works in conjunction with a system application server (such as IBM® WebSphere® Application Server) to provide a layered multiple channel architecture. The application presentation layer works as a bridge that connects the clients with the application logic layer, which performs business transactions. Java clients and HTML clients use different application presentation components to connect to the application logic layer.

To get connected with the application logic layer, the presentation layer defines the following entities:

To pass business process requests to the application logic layer, the application presentation layer has the Invoker Component. The WebSphere Multichannel Bank Transformation Toolkit Invoker Component creates invokers according to the different protocol so that the requester can invoke the EJBs, Web services, POJO or JMS that perform the business processes in the application logic layer.
