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.
Deploying customizations to the IBM Sales Center
Depending on the number of clients and frequency of updates required, you have several choices for installing and updating the IBM Sales Center.
Image installation mechanisms
Technology is available from Microsoft and from external vendors to create an installable image of a preconfigured Windows XP system. The image can be installed on compatible hardware, creating a clone of the original system including any installed applications.
Microsoft Remote Installation Services
Microsoft Remote Installation Services (RIS) is a component of Windows 2000 Server and Windows 2003 Server that supports PXE booting. It can be used to perform a standard Windows XP wizard-based install over the network using an image created on the server by running the Risetup.exe tool. RIS can also install a preconfigured initial load client over the network, using an image captured by running the Riprep.exe tool on an installed and configured Windows XP client. The steps recommended by Microsoft are:

RIS can also install a preconfigured initial load client over the network, using an image captured by running the Riprep.exe tool on an installed and configured Windows XP client. The steps recommended by Microsoft are:

Use Risetup to create a base image on the RIS server
Install the base image on a client machine by PXE-booting from the RIS server
Install and configure additional software to form the prototype initial client software load.
Use Riprep on the client to capture its image onto the RIS server
Install the captured image on other client hardware by PXE-booting from the RIS server
