Registering a Custom Converter

Registering a Custom Converter

As is the case with a custom validator, if the application developer creates a custom converter, you must register it with the application. Here is the converter configuration for CreditCardConverter from the Duke's Bookstore application:

       Converter for credit card
       numbers that normalizes
       the input to a standard format

The converter element represents a Converter implementation and contains required converter-id and converter-class elements.

The converter-id element identifies an ID that is used by the converter attribute of a UI component tag to apply the converter to the component's data. Using a Custom Converter (page 384) includes an example of referencing the custom converter from a component tag.

The converter-class element identifies the Converter implementation.

Creating a Custom Converter (page 405) explains how to create a custom converter.
