import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;
import javax.faces.application.FacesMessage;
public class CreditCardConvert implements Converter{
     public Object getAsObject(FacesContext context,UIComponent component,String newValue) throws ConverterException{
          StringBuilder builderForNewValue=new StringBuilder(newValue);
          boolean foundInvalidCharacter=false;
          char invalidChar;
          int newValueLength=newValue.length();
          int i=0;
          char chFromNewValue;
          while(i<newValueLength && !foundInvalidCharacter){
               chFromNewValue=builderForNewValue.charAt(i);
               if(Character.isDigit(chFromNewValue) || Character.isSpaceChar(chFromNewValue)){
                    i++;
               }else{

                    message.setSeverity(FacesMessage.SEVERITY_ERROR);
                    throw new ConverterException(message);
          return new CreditCard(builderForNewValue.toString());
     public String getAsString(FacesContext context,UIComponent component,Object newValue) throws ConverterException{
          return newValue.toString();

Can anyone help me,TKS!

Answer 1

And besides,if I change the first inputText to:
<td>
<h:inputText id="iptCard" label="card" required="true" value="#{payment.card}">
     <f:convert convertId="com.corejsf.CardConvert"></f:convert>
</h:inputText>
<h:message for="iptCard"></h:message>
</td>
The app runs and result in:
WebContent/index.xhtml @13,55 <f:convert> Tag Library supports namespace: http://java.sun.com/jsf/core, but no tag was defined for name: convert
Is any configuration problem there?
TKS!
