This section provides an example of a JSP that returns content to a REST Web Services client. The JSP invokes a servlet bean to return data that it will incorporate into the output it sends to the REST client. In this example, the JSP uses the /atg/commerce/catalog/ProductLookup component to return repository data to the REST client.

See comprehensive information about developing JSPs for Oracle ATG Web Commerce application in the ATG Page Developer's Guide.

<%-- Import the dsp tag library to access Oracle ATG Web Commerce
     functionality. Import tag libraries for the output format you
     will send to REST clients. --%>

  <%-- Import a servlet bean component you will use with the

  <dsp:importbean bean="/atg/commerce/catalog/ProductLookup"/>
  <dsp:droplet name="ProductLookup">

    <%-- These two parameters are passed to the JSP by the URL
         recoding template. --%>

    <dsp:param name="id" param="productId"/>
    <dsp:param name="aString" param="myString"/>

    <%-- Write the output for REST clients using the values returned
         by the servlet bean. --%>
