How can we built date validation servlet?
On your servlet, you can use something similar to validate the date passed:





protected void doPost(HttpServletRequest request, HttpServletResponse response) {





String date = request.getParameter("date");





if (date == null) || date.equals("")) {


throw ServletException("No date parameter specified");


}





try {


SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");


dateFormat.parse(date);


} catch (ParseException e) {


throw new IllegalArgumentException("Cannot parse date: " + date);


}





// rest of your servlet code


}








In addition, use client-side scripting (e.g. JavaScript) on your JSP pages to do validation before form submission.
