Reg. JFormattedTectField & Date

Question

Hello Friends,
I have a JFTF of Date set to simpleDateFormat(yyyy-mm-dd) format. when the user enters date in some other format - dd-mm-yyyy format, how can i trap that & force the user to enter date in specified format only.
Currently, as said the date format is set to a text field. Suppose the user enteres 11-11-1974,On retriving the text, I get 0017-03-27. While validating date, as it is a valid date, so no errors, but it is wrong. Such date cannot be saved in a database. If again i have to chk the year, day, & month then what the use of this format. So, I want to know, how and when an I trap this invalid/improper format input & inform user to enter data in specified format only. Do i have to handle any event or what?
I am really very curious, wondering about this, and at this point this is the biggest bug in my application. I tried my best to solve this bug, but couldn't find any solution. Does anyone over here have any idea. I would be very thankful for any help.
Thanks

No dear, it doesn't help change any thing. As i had said, on lostfocus, it does some calculations and changes the format & value. Eg. if i enter 11-11-1974, it shows 0017-03-27. So that line makes no changes.
My Code is :-
        // Set the DateFormatter with SimpleDateFormat
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        //sdf.setLenient(true);
        dobFormat = new DateFormatter(sdf);
        dob_tf = new javax.swing.JFormattedTextField();
         // Set Format to the Text Field
         dob_tf.setFormatterFactory(new DefaultFormatterFactory(dobFormat));Do u think, I am going wrong somewhere in the code.
