Make Sure,if you have defined 'POST' in form ,then the corresponding servlet code should be doPost()

Try This:

HTML:

    <form name="data" action="Test" method="POST">
    <label>Birthday: </label> <input type="date" name="dob">
    <input type="submit" value="submit">        
    </form>

Servlet:(inside doPost)

        String date=request.getParameter("dob");
        System.out.println("dateString:"+date);
        Date utilDate=new SimpleDateFormat("yyyy-mm-dd").parse(date); 
        System.out.println("date:"+utilDate);

File HTML/JSP:

<form name="date" action="getDate" method="POST">
   <input type="date" name="dob">
   <input type="submit" value="submit">        
</form>

In file Java:

String dob = (String) request.getParameter("dob");
Date dobDate = new SimpleDateFormat("yyyy-mm-dd").parse(dob);
