How to format a number to "+0000000000.123,45"

Question

Hi! my name is Jorge. My problem is that I need to format a number to a extrange format. I know how to change the decimal point, the number of integer and fraction, etc.
But the problem is I want the number with N zeros at the begining but only with decimal point if there are digit. And I need the sign always appear, if it is a minus or a plus.
For example:
123,456.789 -> +0000000000123,456.789
-1,234,567.890 -> -00000000001,234,567.890
It is possible using a pattern. There is someone who show me how, because I can't find it the rigth pattern.
Thank you very much,
Jorge.

Here play with this - you'll need to tidy it up a bit for numbers under a 1000 or a million - maybe a parseInt function // * here would do it - Anyway, its a start. I've written it in a drag 'n' drop style so you can test and play first beofre applying it. Thats what I usually do - though I seem to recall java programmers think that 'drag-n-drop' is a dirty term - NO OFFENCE GUYS _ I'M NEW !!!
import java.text.*;
public class Decimal_Fmt {
public static void main (String []args) {
double d = Double.parseDouble(args[0]);
DecimalFormat fmt = new DecimalFormat("#0"+","+"000"+","+"000.0#####");
// * Possibly add a function call here ? *
String d_str = fmt.format(d);
System.out.println("DecimalFormat: "+d_str);
}
