The Branch Transformation Toolkit version 5.1 is based on the J2EE standard architecture.
The Java(TM) client side components remain the same as in version 4.3.
The application server tier of the Branch Transformation Toolkit has been split into two layers to separate the presentation from business logic. The application presentation layer, which resides in the Web container of the J2EE environment, now restricts itself to creating requests for business logic hosted within the application logic layer and, for non-Java clients, providing view navigation based on the Apache Struts Framework. The application logic layer performs the business logic requests.
This change enables applications to use more of the capabilities provided by WebSphere(R) Application Server while providing backward compatibility with version 4.3 with minimal migration effort. Version 5.1 of the Branch Transformation Toolkit consists of a set of entirely new components that perform or support a business process or access services and data from the back-end enterprise tier.
