Servlet编程要求：编写Servlet处理表单的程序。要求：熟悉Servlet的基本概念，掌握Servlet的工作原理和生命周期，熟悉Servlet处理表单数据的编程方式，了解Servlet会话管理的编程设计基础。实验内容：1. 编写一个Servlet处理表单的程序，客户端以HTML表单方式向服务器提交数据，提交方法采用Post方法，使用相应方法获取表单数据。2. 程序实现功能如图所示：注意：项目名为ServletProject，表单文件名为test.html，获取表单的Servlet名为testServlet。Index.jsp 潜在用户网络调查 姓名: EMAIL: 年纪: 小于18 18-25 25-40 大于40 编程时间: 小于6个月 6-12个月 大于6个月 使用操作系统: WinXP Win2000/2003 FresBSD MacOS LINUX other 使用编程语言 C C+ C# PYTHON JAVA VB DEPTI 建议: 请在此输入你的建议 Testservlet.javapackage information;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;public class testservlet extends HttpServlet /* * Constructor of the object. */public testservlet() super();/* * Destruction of the servlet. */public void destroy() super.destroy(); / Just puts destroy string in log/ Put your code here/* * The doGet method of the servlet. * * This method is called when a form has its tag value method equals to get. * * param request the request send by the client to the server * param response the response send by the server to the client * throws ServletException if an error occurred * throws IOException if an error occurred */public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException response.setContentType(text/html;charset=GB2312); PrintWriter out = response.getWriter(); byte b1=request.getParameter(myname).getBytes (ISO-8859-1);String s1=new String(b1,UTF-8);byte b2=request.getParameter(email).getBytes(ISO-8859-1); String s2=new String(b2,UTF-8); byte b3=request.getParameter(age).getBytes(ISO-8859-1); String s3=new String(b3,UTF-8);byte b4=request.getParameter(time).getBytes(ISO-8859-1); String s4=new String(b4,UTF-8); String b5=request.getParameterValues(system); HttpSession session1=request.getSession(true); session1.setAttribute(st,);for(int i=0;ib5.length;i+) session1.setAttribute(st,session1.getAttribute(st)+b5i+ ); String s=(String)session1.getAttribute(st);byte f2=s.getBytes(ISO-8859-1);String s5=new String(f2,UTF-8);String b6 = request.getParameterValues(language); HttpSession session=request.getSession(true); session.setAttribute(str,);for(int i=0;ib6.length;i+) session.setAttribute(str,session.getAttribute(str)+b6i+ ); String ss =(String)session.getAttribute(str);byte f1=ss.getBytes(ISO-8859-1);String s6=new String(f1,UTF-8);byte b7=request.getParameter(suggest).getBytes(ISO-8859-1); String s7=new String(b7,UTF-8);out.println();out.println(用户的信息);out.println(姓名: +s1+); out.println(EMAIL:+s2+); out.println(年纪: +s3+);out.println(编程时间: +s4+);out.println(使用操作系统: +s5+);out.println(使用编程语言: +s6);out.println();out.println(建议: +s7+);out.print
