The topics in the Developing section describe tasks performed by an application developer.
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.
Procurement system integration
WebSphere Commerce provides the capability to integrate with procurement systems. This capability enables WebSphere Commerce customers to participate as suppliers in the procurement system's marketplace, increase sales, and enhance their business-to-business presence on the Web. WebSphere Commerce provides an extensible and customizable functionality in such a way that one can extend either the messages or the business logic.
Adding a new message mapper for procurement
Procurement systems that use the XML/HTTP protocol need to have a message mapper in order to communicate successfully with WebSphere Commerce.
