Controller layer
The Controller layer is the conductor of operations for a request. It controls the transaction scope and manages the session related information for the request. The controller first dispatches to a command and then calls the appropriate view processing logic to render the response.
Integrating with back-end systems and external applications
External systems integration is a key feature of the WebSphere Commerce solution. In WebSphere Commerce business logic is enabled for integration and built-in adapters and interfaces are provided for common integration points. Additionally, the WebSphere Commerce integration solution leverages integration standards by using various IBM connectivity solutions.
Customizing WebSphere Commerce Payments
Cashier function in WebSphere Commerce Payments
The Cashier function is a Java class provided with WebSphere Commerce Payments. WebSphere Commerce uses the Cashier function to simplify the process of creating orders and payments. This component increases the flexibility available for payment processing when payment cassettes are used. The Cashier interacts with the merchant server and the WebSphere Commerce Payments framework, so that these two components are independent. As such, you do not have to modify the merchant server in order to adopt any new cassettes or custom cassettes for new payment methods. The mechanism that makes this possible are the Cashier profiles.
