Formatting a given currency for various locales in java? (Rounding issue)

I am trying to format a currency based on the accept-language header, but I'm having a little trouble.

  1. An English-US user will understand € 10,000,000.15 but not the suitable-for-Germany equivalent, € 10.000.000,15

  2. On the other hand, "$23,123 looks" fine to an English-US user, but "$23,123.00" looks very strange. So does "JPY23,123.00". The latter is what I get using the following code:

     java.text.NumberFormat format = java.text.NumberFormat.getCurrencyInstance(java.util.Locale.US);
 format.setCurrency(java.util.Currency.getInstance("JPY"));

  3. Even more disturbing is the rounding that happens when I display USD in ja_JP. if I format 7.95, it just shows as "USD8" instead of "USD7.95"

Is there any simple way to avoid this? Is there a better library for formatting currencies? Should I just format it as a number for the locale (if the currency isn't the locale's default), and then prepend the currency code or symbol?

By default 10000000.15 euro is printed as EUR10,000,000.15 for Locale.US and 10.000.000,15 € for Locale.GERMANY and it seems correct.

But USD8 for $7.75 looks really weird even for Japan. But this can be fixed:

    NumberFormat format = NumberFormat.getCurrencyInstance(locale);
    format.setCurrency(currency);
    format.setMaximumFractionDigits(currency.getDefaultFractionDigits());
    System.out.println(format.format(7.95));

it prints USD7.95 for JAPAN/USD and JPY8 for US/JPY
