2.Use Table 8-1 on page 133 to identify the WebSphere Commerce V5.6 interface that match the WebSphere Commerce Suite V5.1 interface used in the previous step.

In our example, the WebSphere Commerce V5.6 interface is com.ibm.commerce.order.calculation.ApplyShippingCmd.

3.Create a custom interface, extending the the WebSphere Commerce V5.6 command interface. Add two constants, NAME and defaultCommandClassName to the interface, containing the name, including package, of the custom interface and the implementing class, respectively. The implementing class is created in the next step.

Example 8-4 Sample MyApplyShippingCmd

package mypackage;

public interface MyApplyShippingCmd

extends com.ibm.commerce.order.calculation.ApplyShippingCmd

{

public static final String NAME = “mypackage.MyApplyShippingCmd“; public static final String defaultCommandClassName =

“mypackage.MyApplyShippingCmdImpl“;

}

4.Create a custom class, implementing the interface created in the previous step and extending from the WebSphere Commerce V5.6 command implementation class. Refer to “Interface changes” on page 139 for details about the interface changes from WebSphere Commerce Suite V5.1 to WebSphere Commerce V5.6.

Our resulting implementation class is shown in Example 8-5.

Example 8-5 Sample MyApplyShippingCmdImpl

package mypackage;

import java.util.Set; import java.util.HashSet;

public class MyApplyShippingCmdImpl

extends com.ibm.commerce.order.calculation.ApplyShippingCmdImpl implements MyApplyShippingCmd

{

private static final long COMPONENT = ECTraceIdentifiers.COMPONENT_EXTERN; private Item[] iItems = new Item[0];

private Set iAppliedItems = new HashSet();
