<%@ page contentType="text/html;charset=UTF-8" language="java" %>


<%
    String s  = request.getParameter("name");
    System.out.println(s);
%>

Do you know what am i doing wrong ?

Solution

  • This line allows you to get a parameter with its name not its id :

     String s  = request.getParameter("name");

    Add a name to your input and correct the typo of the attribute action of your form : 

      <form action="addnewtask.jsp" method="post" >
      <label for="name">Name</label>
      <input name="name" type="text" class="form-control" id="name" placeholder="Name">
      <button type="submit" class="btn btn-danger">Add</button>
  <form>
