On a JSP page, you can use the /atg/commerce/endeca/cache/DimensionValueCacheDroplet component (of class atg.commerce.endeca.cache.DimensionValueCacheDroplet) to obtain the dimension value associated with a specific category. This servlet bean takes the following input parameters:
repositoryId
The repository ID of the category to retrieve the correspondingDimensionValueCacheObjectfor.
ancestors
A list of the repository IDs of the category’s ancestor categories, delimited by colons. This value helps determine the correctDimensionValueCacheObjectto retrieve for a category that has more than one path in the catalog hierarchy.
DimensionValueCacheDroplet returns the DimensionValueCacheObject entry that matches these parameters. For example:
<dsp:droplet name="DimensionValueCacheDroplet">
<dsp:param name="repositoryId" value="${categoryId}"/>
<dsp:param name="ancestors" value="${topLevelCategoryId}"/>
<dsp:oparam name="output">
<dsp:getvalueof var="categoryCacheEntry" param="dimensionValueCacheEntry" />
</dsp:oparam>
</dsp:droplet>The url property of the DimensionValueCacheObject can be used to render a link to an Assembler-driven category page. For example:
<dsp:a page="${categoryCacheEntry.url}">
<dsp:valueof value="${categoryDisplayName}">
<fmt:message key="common.categoryNameDefault" />
</dsp:valueof>
</dsp:a>
