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
WebSphere Commerce Payments framework architecture and cassettes
WebSphere Commerce Payments implements a multi-payment framework architecture that provides a flexible and extensible way to accommodate payment requirements on the Internet for merchants who need to accept multiple payment methods. This multi-payment framework separates the infrastructure and processes of payment management from specific payment types by using of software cassettes. These cassettes contain the specifics of handling a type of payment method. Cassettes translate the generic WebSphere Commerce Payments messages into payment-protocol specific messages which are then sent to the appropriate payment gateway (or Acquirer) for further processing. Each cassette provides support for a specific electronic payment system, and the framework can handle multiple cassettes simultaneously.
Enabling a new cassette
You may want to enable new cassettes to WebSphere Commerce Payments to handle new payment methods or customize the way certain payments are handled. You can either create the cassettes yourself or obtain them from a third party.

Enabling a new cassette

You may want to enable new cassettes to WebSphere Commerce Payments to handle new payment methods or customize the way certain payments are handled. You can either create the cassettes yourself or obtain them from a third party.

For each new cassette, you need to provide a Cashier profile. The Cashier profile may already be provided if you obtain a cassette from a third party.
Update this Cashier profile or, if you created the cassette, create your own Cashier profile.
Configure the cassette and Cashier profile.
Create a payment policy for the related store.
