The store.war/cartridges/HeaderBanner-ATGCategory/HeaderBanner-ATGCategory.jsp page renders the content in the CategoryHeaderBannerContentItem object. This renderer retrieves the headerTitle and headerBannerURL values from the CategoryHeaderBannerContentItem object and uses these values to render the display name and background image for the banner. HeaderBanner-ATGCategory.jsp also retrieves the promotionalContentId value and passes it to the /atg/commerce/promotional/PromotionalContentLookup component to render the promotional content item. This component is of class atg.commerce.catalog.custom.CatalogItemLookupDroplet and it specifies the catalog repository as the repository to be searched and promotionalContent as the item type to search for.

When a promotional content item that includes a link is clicked, it takes the shopper to the page specified in the promotional content item’s associatedCategory property. The link for this page must be constructed using an Endeca URL. To satisfy this requirement, the template used to render promotional content items, store.war/promo/gadgets/linkedImage.jsp, uses the <crs:promotionalContentWrapper.tag>. This tag calls the /atg/commerce/endeca/cache/DimensionValueCacheDroplet servlet bean to retrieve the correct URL for the associatedCategory and then it associates that URL value with the link reference.

Note: See the ATG-Endeca Integration Guide for information about the DimensionValueCacheDroplet servlet bean and the cache.
