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> <description> Converter for credit card numbers that normalizes the input to a standard format </description> <converter-id>CreditCardConverter</converter-id> <converter-class> com.sun.bookstore6.converters.CreditCardConverter </converter-class> </converter>
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.
