OK so what I did is:
--jsp---
<input name="price" value="<bean:write name="Obj" property="price"
format="##"/>" />
-> Value gets displayed with commas.
--action-form-
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.GERMAN);
DecimalFormat df = (DecimalFormat) nf;
df.setDecimalSeparatorAlwaysShown(false);
df.applyPattern("#,###,###,###,###.#########");
if (price != null) {
if (price.contains(".")) {
ActionError msg = new
ActionError("servlets.jsp.error.edit1");
errors.add("uploadErr", msg);
System.out.println("error");
} else {
ParsePosition pp2 = new ParsePosition(0);
Number inNbr = df.parse(price, pp2);
setPriceDouble(inNbr.doubleValue());
}
}
In my struts action form I check for null values and the copy the string
representation into a double value.
Does that make sense?
