Question

I have a currency field which has length > 20 digit

E.g : 99999999999999999999

and when i used:

<fmt:formatNumber
     value="${crudShipmentForm.invoiceVat}"
     pattern="###,###,###,###,##0.000"  />

I received NumberFormatException ?
How can I format this field to currency using fmt:formatNumber ?

Answer 1

Your number is too large.

Here’s the relevant code from FormatNumberSupport:

if (input instanceof String) {
    try {
    if (((String) input).indexOf('.') != -1) {
                // String value is interpreted as a double
        input = Double.valueOf((String) input);
    } else {
                // String value is interpreted as a long
        input = Long.valueOf((String) input);
    }
    } catch (NumberFormatException nfe) {
    throw new JspException(
                Resources.getMessage("FORMAT_NUMBER_PARSE_ERROR", input),
        nfe);
    }
}

Your number is way beyond the scope of long
