Dialogs are a common user interface element in the IBM Sales Center. Dialogs are used when the user chooses to perform an action and needs to provide additional information. For example, the interface that a customer uses to log on, or search for an order, are dialogs.

The contents of dialogs are user interface elements known as controls and managed composite controls.

Customization of these dialogs involves using the Eclipse product extension point architecture. The following sample demonstrates how to extend the Logon dialog. This demonstrates how you can replace an existing Sales Center dialog class with a new dialog class. Normally this is not necessary because you can use controls and managed composite controls extensions and the system configurator to make changes to existing dialogs without replacing the dialog implementation. In our example, the extension is defined in a new plug-in called extensions:

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
      <configurator path="config"/>
   <extension point="com.ibm.commerce.telesales.ui.dialogs">
<!-- Logon Dialog -->

Below is the Java implementation class:


package extensions;

import com.ibm.commerce.telesales.ui.impl.dialogs.LogonDialog;

public class ExtendedLogonDialog extends LogonDialog {
         * Write out to the console to indicate that
         * that the extended dialog is being used.
        public ExtendedLogonDialog() {

The system configurator extension point is used to indicate that the new dialog will be used:
