        DateFormat dateformatYYYYMMDD = new SimpleDateFormat("yyyyMMdd");
    String nowYYYYMMDD = new String( dateformatYYYYMMDD.format( dateChooser.getDate()) );
    textField_1.setText(nowYYYYMMDD);

My guess is that dateChooser.getDate() is returning null, given the stack trace. We can't tell why that is from the code you've given us.

Note that you're calling this from your Remontas constructor - is that deliberate?

use this code, it worked for me ps.setString(1, ((JTextField)txtDate.getDateEditor().getUiComponent()).getText());
