myservlet.java

可以实现app的简单实现

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;

public class MyServlet extends HttpServlet{

	private String target = "/hello.jsp";

	public void init(ServletConfig config) throws ServletException{
		super.init(config);
	}

	public void doGet(HttpServletRequest request,HttpServletResponse response)
    throws ServletException, IOException{
		doPost(request, response);
	}

	public void doPost(HttpServletRequest request,HttpServletResponse response)
    throws ServletException, IOException{
		
		String username = request.getParameter("username");
		String password = request.getParameter("password");

		request.setAttribute("USER", username);
		request.setAttribute("PASSWORD", password);

		ServletContext context = getServletContext();

		System.out.println("Redirecting to " + target);
		RequestDispatcher myservlet = 
			context.getRequestDispatcher(target);
		myservlet.forward(request, response);
	}

	public void destroy(){
	}
}
