Developing
The topics in the Developing section describe tasks performed by an application developer.
Presentation layer
WebSphere Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
Customizing IBM Sales Center
In the IBM Sales Center for WebSphere Commerce there is a set of user interface panels, views and dialogs that contain the most commonly used features. You can add to or configure the user interface to suit your needs, as well as changing the content and format of the data that is passed between the client and the server.
Menu actions
The default IBM Sales Center actions are defined by the com.ibm.commerce.telesales.ui.actionSetGroups extension-point. This extension point allows you to specify a list of actionSet IDs and an ID for the whole group. When a IBM Sales Center perspective is loaded, it will use a predefined ID to determine which action set group to use. You can use the system configurator plug-in to override an entire action set group, or a specific action set that already defined as part of the action set. All of the out of the box IBM Sales Center menu items delegate their actual work to an action that is registered with the com.ibm.commerce.telesales.ui.actions extension point. This allows you to use the system configurator to replace the implementation of a single action.
