Blank result for jsp_servlet in Eclipse

Hello all,

Greetings!!!

I am new to this forum and also to Eclipse..

Have created index.jsp under WebContent in Eclipse. Having firstname and surname text boxes with submit button. Contents look like :

Code:

<form action="GreetingServlet" method="POST"> First Name: <input type="text" name="firstName" size="20"><br> Surname: <input type="text" name="surname" size="20"> <br><br> <input type="submit" value="Submit">

and created GreetingServlet by right clicking ProjectName(HelloServlets) -> New -> Projects -> Servlet
Contents look like:

Code:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter out = response.getWriter(); String firstName = request.getParameter("firstName").toString(); String surname = request.getParameter("surname").toString(); }

The problem is that, variables out,firstName,surname are underlined with yellow line in Eclipse's default browser . and when i keep the cursor on that variables then it displays warning message like "The local variable is never read".

SO i guess no contact between jsp and servlet files.. but when i submit the page is directing to http://localhost:8080/HelloServlets/GreetingServlet

but its blank .. Pls Help to execute this program correctly in Eclipse

Thanks in advance

The warning appears because you don't write the lines to print the first name and surname.

Code:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter out = response.getWriter(); out.println("<title>Example</title>" + "<body bgcolor=FFFFFF>"); out.println("<h2>Button Clicked</h2>"); String firstName = request.getParameter("firstName").toString(); String surname = request.getParameter("surname").toString(); if(firstName != null){ out.println(firstName); } else { out.println("No text entered."); } if(surname != null){ out.println(firstName); } else { out.println("No text entered."); } }
