hi, I'm trying to run my 1st servlet I'm using eclipse and tomcat
but I get an error that I cannot solve. can anyone tell me what I'm missing?

here is my index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>

<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">
</form>


</body>
</html>

and here is my servlet

GreetingServlet.java

package J;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

/**
 * Servlet implementation class GreetingServlet
 */
public class GreetingServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;

    /**
     * Default constructor. 
     */
    public GreetingServlet() 
    {
        // TODO Auto-generated constructor stub
    }

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
	{
		response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        String firstName = request.getParameter("firstName").toString();
        String surname = request.getParameter("surname").toString();

        out.println("<html>");
        out.println("<head>");
        out.println("<title>Servlet GreetingServlet</title>");
        out.println("</head>");
        out.println("<body>");
        out.println("<h1>Servlet GreetingServlet at " + request.getContextPath () + "</h1>");
        out.println("<p>Welcome " + firstName + " " + surname + "</p>");
        out.println("</body>");
        out.println("</html>");

        out.close();
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
	{
		String firstName = request.getParameter("firstName").toString();
        System.out.println("firstName = " + firstName);
	}

}

When ever I run it I get this error
