Question

I have a simple Jsp page which contains HTML elements,as follows,

<tr id="tr-username">
   <td>Username</td>
   <td><input type="text" id="userName"/></td>
</tr>

I want to set the value of userName textbox to a session variable.How to do that?

Answer 1

You cannot directly set the value in the session variable from the rendered JSP . Once your form on jsp is submitted then at the servlet/controller you can do :

 String userName = request.getParameter("userName");
   if(userName!=null && !"".equals(userName){ 
         request.getSession().setAttribute("userName",userName);
   }
