Hi again
Unfortunately I also don't have that function, I had written it for my
previous job. But it was not a complicated thing.
To parse the number; first replace thousands seperator with nothing then
replace decimal seperator with "." then parse the number.

I wrote a sample now

    public void numberSample() {
          String x=new String("1.000.000,2");
          java.text.DecimalFormatSymbols sym=new
java.text.DecimalFormatSymbols();
          System.out.println("Grouping
seperator="+sym.getGroupingSeparator());
/* if thousands seperator is "." then we must escape it by \ because it is a
special character for regular expressions, and \ is escape character in
strings and goes on :)
*/
          String
re=(sym.getGroupingSeparator()=='.'?"\\":"")+sym.getGroupingSeparator();
          x=x.replaceAll(re,"");
          System.out.println("After grouping removed: "+x);
          x=x.replace(sym.getDecimalSeparator(),'.');
          System.out.println("Finally: "+x);
          System.out.println("Double parsed:"+Double.parseDouble(x));
    }

Hope this helps
Serkan
