Welcome to the WebLogic Commerce Server Components Tour! This is a step-by-step walk-through of the My BuyBeans.com demo from a components development perspective. Learn-by-doing to modify WebLogic Commerce Server EJB components to extend custom business policies. Consider an online product catalog filled with items that have different descriptions, attributes, identifiers, and prices. Since many items have different attributes, they need to be stored differently. However, items do share some common attributes. Now imagine adding a new product line to the catalog with new features, attributes, and pricing schemes. It is in a case like this where customizability and extensibility play big roles. Enter BEA's WebLogic Components!
