Validating monetary input fields

Question

Hi. We are developing a web site that supports English and French. Some of the web pages have forms where the user must enter monetary values. Since English and French monetary values use different formats, I am wondering if there's a Java API (that hasn't been deprecated or is obsolete) that would perform validation of these monetary values for us rather than us having to write these from scratch (granted, it would not be overly difficult)? I looked through the Internationalization tutorial but did not see anything on processing currency input, just on output formatting based on the locale (which works fine for us). Thanks...

When I run the following program:
import java.text.NumberFormat;
import java.text.ParseException;
import java.util.Locale;
public class frmoney
    public static void main(String[] args)
     String number = (args.length < 1) ? "24,98" : args[0];
     NumberFormat nfc = NumberFormat.getCurrencyInstance(Locale.FRENCH);
     try {
         System.out.println("Parsing " + number);
         System.out.println(nfc.parse(number));
     catch (ParseException e)
         System.out.println(e);
}I get:
Parsing 24,98
java.text.ParseException: Unparseable number: "24,98"
