Class ShoppingCartAttributeLoader

java.lang.Object
  com.bea.campaign.ShoppingCartAttributeLoader

All Implemented Interfaces:

Request.AttributeLoader

Direct Known Subclasses:

ShoppingCartAttributeLoader

public class ShoppingCartAttributeLoader

extends Object

implements Request.AttributeLoader

A p13n request attribute loader which will load the ShoppingCart into the p13n request.

This will, by default, pull the shopping cart from the pipeline session at a session attribute "wlcs_shoppingCart", and, if found, set it in the p13n Request at an attribute called "wlcs_shoppingCart". The attribute names are controlled by the getShoppingCartSetName(), getShoppingCartNamespace(java.lang.Object), and getShoppingCartGetNames() method.

To use this class, register it in your application-config.xml in the following places:

• put the fully-qualified class name in the <AttributeLoader RequestLoaders="..."> attribute.
• put the return value of getShoppingCartSetName() (defaults to "wlcs_shoppingCart") in <ScenarioService RulesRequestAttrNames="..."> attribute.
