具体步骤的主要代码，按逻辑顺序：
取得用户的资料需要建立一个javabean：RegisterBean.java,，和一个severlet:
RegisterSeverlet. 这个SEVERLET来调用这个BEAN，来判断用户的输入，是否合乎要求。注册失败后显示错误页:erro.jsp。注册成功显示用户资料页：show.jsp
(1)连接数据库代码
   public void init() throws ServletException {
    try {
     BYSJDB.connectToDB();
    }
    catch (Exception e) {
      System.out.println("数据库连接失败！");
      throw new ServletException(e.getMessage());
    }
(2)取得用户输入
String qyID = request.getParameter("qyID");
    String leixing = request.getParameter("leixing");
String farenDB = request.getParameter("farenDB");
String yingyongLX = request.getParameter("yingyongLX");
    String password = request.getParameter("password");
    String repassword = request.getParameter("repassword");
    
    String city = request.getParameter("city");
    String tel = request.getParameter("tel");
    String Email = request.getParameter("Email");
    String address = request.getParameter("address");
    String qymc = request.getParameter("qymc");
String yyzh=request.getParameter("yyzh") ;
String qyjj=request.getParameter("qyjj") ;
(3)对用户资料填写的判断
   if (password.equals(repassword) && email.indexOf("@") != -1) {
      //口令 & email效验通过
    try {
           ManageDB.restaurantRegister(qyID, leixing, farenDB,yingyongLX,
                                      city, tel, Email, password,address,
                                    qymc,yyzh,qyjj);

}
(4) 注册失败转向erro.jsp
    <%System.err .println("...error.jsp...") ;%> error.jsp An error occured in the bean. Error Message is: <%= exception.getMessage() %>Stack Trace is : <%
    java.io.CharArrayWriter cw = new java.io.CharArrayWriter();
java.io.PrintWriter pw = new java.io.PrintWriter(cw,true);
    exception.printStackTrace(pw);
    out.println(cw.toString());
%>
(5) 注册成功转向show.jsp
取得数据库中当前用户的资料显示在show.jsp页面中。

但是老师要求生成ＸＭＬ的文档，该对代码做怎样的修改呢？？？
请高手帮助我拉！！谢谢拉
