Tutorial: Customizing Web 2.0 and Web services to support personalization

This tutorial extends the OrderItem Web services noun to include new information. Overlays are used to transfer the new order information from the Madisons starter store to WebSphere Commerce, where it persists to the database.

Learning objectives

In this tutorial, we will customize the shopping flow to allow the customer the ability to keep track of engraving information for an order item. After this customization, a customer will have an option to engrave items in their shopping cart that can be engraved. For example, wine glasses will have the option to be engraved, with the shopper specifying the size and font of the text. You learn the development steps that are common to extending the noun using overlays, as well as using access beans to persist and retrieve the new data.

Time required

Expect this tutorial to take about 4 hours to complete.

Lessons in this tutorial

• Prepare the database for new engraving attributes
  In this step, you create engraving attributes.

• Create the SDO genmodel file
  In this step we will create an genmodel file that will be used to generate the new EngravingOrderItemType object.

• Generate the SDO code from the genmodel file
  In this step we will generate the new Service Data Object from the genmodel file.

• Use the new SDO to customize the client library and component facade
  This section explains using the new SDO to customize the client library and component facade.
