JSP files can retrieve and display information from WebSphere
Commerce services using the getData tag.
About this task
Tip: The starter store pages, such as Consumer
Direct JSP files, use the data bean programming model for data retrieval.
For example, existing starter store pages, such as ProductDisplay.jsp,
do not use the getData tag. However, you can add getData tags to these
pages retrieve additional information from your WebSphere Commerce
services.
Procedure
- Open WebSphere Commerce Developer.
- In the Enterprise Explorer view,
navigate to .
Continue navigating to the subfolder where the JSP file you want to
customize is located.
- Locate the section of the page where you want to retrieve
data, and add a getData tag, similar to the following example.
In this example, the getData tag populates a variable named catentries
with
the data returned by a custom expression builder named getCatalogEntryWithWarranty
.
The custom access profile MyCompany_All
is provided
as a parameter to control the amount of data that is returned about
each object.
<wcf:getData var="catentries" type="com.ibm.commerce.catalog.facade.datatypes.CatalogEntryType[]"
expressionBuilder="getCatalogEntryWithWarranty">
<wcf:contextData name="storeId" data="${WCParam.storeId}"/>
<wcf:contextData name="catalogId" data="${WCParam.catalogId}"/>
<wcf:contextData name="langId" data="${WCParam.langId}"/>
<wcf:param name="catalogEntryId" value="${WCParam.catalogEntryID}"/>
<wcf:param name="accessProfile" value="MyCompany_All"/>
</wcf:getData>
For reference information about the getData tag, see
Tag: getData.
- Optional: If the getData tag returns a collection
of objects, you can iterate over them using a forEach loop tag, similar
to the following example:
<c:forEach var="catalogEntry" items="${catentries}">
<!-- present details about each catalogEntry object in catentries -->
</c:forEach>
