alright so here are my 2 servlets. my login page is suppossed to redirect to the mynotes page after a successsful login. I use useresponse.sendRedirect("/Homework2/MyNotes"); in my login page at the bottom to try and accomplish that , but it doesnt work. my guess was because these belong to 2 different packages. which is homework1 and homework2. so my question is how can I map it so that my login page directs the user to the mynotes page? If i put Mynotes in my homework1 package , it works perfectly , so It has to be because its 2 different packages. but i have no idea how to make it work.

also , the error i get is HTTP Status 404 - /cs320stu38/Homework1/MyNotes

which means its still sending to the homework1 package , how can i change it so that its the homework2 package?

package cs320.Homework1;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

@WebServlet("/Homework1/Login")
public class Login extends HttpServlet {
	private static final long serialVersionUID = 1L;

protected void doGet(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {

response.setContentType("text/html");
		PrintWriter out = response.getWriter();

out.println("<!DOCTYPE html>");
		out.println("<html>");
		out.println("<head>");
		out.println("	<meta charset=\"UTF-8\">");
		out.println("	<title>Login</title>");

		out.println("</div>");
		out.println("<div class=\"row\">");
		out.println("<div class=\"col-sm-offset-3 col-sm-6\">");
		if (request.getAttribute("Error") != null) {
			out.println(request.getAttribute("Error") + "<br/>");

}
		out.println("<form action=\"Login\" method=\"post\">");
		out.println("<form class=\"form-signin\">");
		out.println("<h2 class=\"form-signin-heading\">Please Sign In</h2>");
		out.println("<label for=\"email\" class=\"sr-only\">Email address</label>");
		out.println("<input type=\"email\" name=\"email\" id=\"email\" class=\"form-control\" placeholder=\"Email Address\" />");
		out.println("<label for=\"password\" class=\"sr-only\">Password</label>");
		out.println("<input type=\"password\" name=\"password\" id=\"password\" class=\"form-control\" placeholder=\"Password\" />");
		out.println("<div class=\"checkbox\">");
		out.println("<label>");
		out.println("<input type=\"checkbox\" name=\"remember\" value=\"yes\"> Remember Me");
		out.println("</label>");
		out.println("</div>");

		out.println("</form>");
