The topics in the Developing section describe tasks performed by an application developer.
Presentation layer
WebSphere Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
IBM Product Recommendations and WebSphere Commerce
IBM Product Recommendations is an IBM Digital Analytics solution that you can subscribe to that automatically generates personalized product recommendations on the storefront. The recommendations are based on the browsing, shopping, and purchasing behavior of individual customers. If your site is integrated with IBM Digital Analytics, you can display recommendations from IBM Product Recommendations on your store pages.
Data extraction utility for dynamic recommendations in IBM Product Recommendations
The Intelligent Offer data extraction utility is a command-line utility that you can use to create the Enterprise Product Report (EPR) data for dynamic recommendations that is required by IBM Product Recommendations, formerly known as Coremetrics Intelligent Offer. The utility extracts catalog data from your database and generates ECDF and EPCMF files in the correct format to load into IBM Product Recommendations. You can provide these two files to IBM Product Recommendations regularly for processing dynamic recommendations.
Customizing the IBM Product Recommendations data extraction utility
If the default EPCMF file output by the data extraction utility for IBM Product Recommendations, formerly known as Coremetrics Intelligent Offer does not meet your business needs, you can customize the utility.
...extracting category-level SKUs
If your catalog contains category-level SKUs, you can customize the data extraction utility to include these SKUs in the EPCMF file. This customization involves adding a custom query template file that defines a new SQL query to extract category-level SKUs, extending a Java class, and then updating configuration files to use your extended Java class.
Updating the business object configuration file to use the extended data reader class
The business object configuration file, wc-dataextract-catalog-entry.xml, points to the default data reader class, CatalogEntryReaderMediator. You must update the configuration file to point to your new extended data reader class instead.

Introduced in Feature Pack 3

Updating the business object configuration file to use the extended data reader class

The business object configuration file, wc-dataextract-catalog-entry.xml, points to the default data reader class, CatalogEntryReaderMediator. You must update the configuration file to point to your new extended data reader class instead.

Before you begin

Ensure that your business object configuration file for EPCMF data is already in the correct directory and configured for your site according to the instructions in Configuring the IBM Product Recommendations data extraction utility.
Review the following topic to understand the contents of the business object configuration file for EPCMF data:
Sample business object configuration file for EPCMF data

Procedure

Open your business object configuration file for EPCMF data at the following path:
- WCDE_installdir/samples/DataExtract/Catalog/CatalogEntry/wc-dataextract-catalog-entry.xml
- WC_installdir/samples/DataExtract/Catalog/CatalogEntry/wc-dataextract-catalog-entry.xml

Locate the following line of code, which specifies the data reader class that the utility uses:

<_config:DataReader className="com.ibm.commerce.catalog.dataload.datareader.CatalogEntryReaderMediator" pageSize="700" >

Replace the className value with the name of your extended data reader class, as shown here:

<_config:DataReader className="com.ibm.commerce.catalog.dataload.datareader.ExtCatalogEntryReaderMediator" pageSize="700" >

Save and close the configuration file.
Test your customization by running the data extraction utility and viewing the EPCMF file that contains your category-level SKUs. For more information, see Running the IBM Product Recommendations data extraction utility.
