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.
Management Center framework
The Management Center framework is the foundation for business user tooling. The business objects are defined by the individual components that make up the Management Center. The framework uses those definitions to provide all of the features that you can use to find, create, modify, and delete the defined business objects. If you plan to customize the Management Center, it is important to understand the framework and the components that make up the Management Center.
Customizing the Management Center user interface
Customize the Management Center user interface by adding, changing, or removing elements within the user interface.
Resource access control
Some objects that are loaded by the Management Center framework should not be edited by a business user. Mark these objects as read-only by adding readonly="true" to the serialized object. For example, active promotions can be viewed, but not changed.

Resource access control

Some objects that are loaded by the Management Center framework should not be edited by a business user. Mark these objects as read-only by adding readonly="true" to the serialized object. For example, active promotions can be viewed, but not changed.

The read-only state of a child object is inherited from its parent object, but can be overridden if the child object has a different read-only state from its parent. Primary objects do not inherit the read-only state of the reference objects that reference them.
