Specifying Custom Converters in JSF Pages

• Give the converter an ID in faces-config.xml:

       <converter>
          <converter-id>com.corejsf.CreditCard</converter-id>
          <converter-class>com.corejsf.CreditCardConverter</converter-class>
       </converter>
  

• Use the ID in an input tag:

       <h:inputText value="#{payment.card}">
          <f:converter converterId="com.corejsf.CreditCard"/>
       </h:inputText>
  

Using a value expression:

• Use the converter attribute that yields a converter object:

       <h:outputText value="#{payment.card}" converter="#{bb.convert}"/>
  

• This requires a backing bean that returns an anonymous class object.
