Answer 1

Thanks Ralph. I did some further digging around and came up with this (Which goes in my form controller):

    @InitBinder
    public void initBinder(WebDataBinder binder) {


    String format = "dd/MM/yyyy";
    SimpleDateFormat dateFormat = new SimpleDateFormat(format);
    dateFormat.setLenient(false);
    CustomDateEditor customDateEditor = new CustomDateEditor(dateFormat,true,format.length());

    binder.registerCustomEditor(Date.class, customDateEditor);
    }

With the properties file having the following key:

typeMismatch.java.util.Date : Some nice calm reassuring message to assist all negligent users

Maybe there are some other ways to do this but this will do for now.

You can not do this with JSR303, because the validation runs on the already poplulated (form baching) object.

So you need to implement your own custom converter, that is a bit more strickt than the one shipped with spring.
