Developing
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.
Distributed Order Management (DOM) integration
DOM integration enhances the shopping flow in the Aurora starter store, while enhancing backend system integration with WebSphere Commerce. This integration provides comprehensive coverage of the order lifecycle across channels, from capture to fulfillment.
Building a WebSphere Enterprise Service Bus mediation module for DOM integration
Building a simple, yet functional, WebSphere Enterprise Service Bus mediation module for DOM integration by using WebSphere Integration Developer introduces you to several key concepts. These concepts include working with WebSphere Integration Developer as a development platform, working with mediation flows, and using XSL transformation primitives in mediation flows to transform WebSphere Commerce OAGIS BOD messages to and from messages in the backend system's format.

About this task

The external OMS simulator is a simple JEE application that is written to serve as a sample backend system for DOM integration purposes. It imitates an authentic backend system by exposing a number of inventory and order operations, for example, inventory reservation and order creation, as web services.

However, the external OMS simulator does not perform any real processing or logic when the simulator generates data for return. It instead returns standard or random results, depending on the case, to use as sample sets of data. For more information, see Install the external OMS simulator for more information.

Note: You are recommended to a WebSphere Enterprise Service Bus on a 64-bit system. Out of memory issues can be encountered if you are installing on a 32-bit environment.
