Messed Up Date Validation In 1.1.7

[Ryan Sutter]

I don't know for sure that this specific to Linux Java so my apologies
in advance.  I am using this code for date validation:

                DateFormat df = new SimpleDateFormat("MM/dd/yyyy");
                try {
                    Date theDate = df.parse(theText);
                    jtf.setText( df.format( theDate )); //??!!
                } catch (ParseException pe) {
                    System.out.println(pe);
                    jtf.setText("");
                    jtf.repaint();
                }

This method allows incorrect dates like 13/9/98 without complaining.  My
testers are complaining though.  :-)  Does anybody know of a better/more
accurate date validation class out there?  Or a better way to use this
one?

Thanks in advance,

Ryan
