}出错的Servlet 源代码！

在Form里呢package my.protect.view;import javax.servlet.http.HttpServlet;

    public void doPost(HttpServletRequest request,

    public void generateView(HttpServletRequest request,

            out.println("</head>");
            out.println("<body>");
             if(errorMsgs!=null){
            out.println("<p>");
        out.println("<font color='red'><ul>");
        Iterator items = errorMsgs.iterator();
        while ( items.hasNext() ) {
            String errorMsg = (String) items.next();
            out.println("  <li>" + errorMsg + "</li>");
        }

            String Name=request.getParameter("Name");
            if(Name==null){
                Name="";
            }
            out.println("Name:<input type='text' name='Name' value='"+Name+"'/><br/><br/>");
            String Age=request.getParameter("Age");
            if(Age==null){
                Age="";
            }

            String Province=request.getParameter("Province");
            if(Province==null){
                Province="";
            }

            out.println("Interests:<input type='text' name='Interests' value='"+Interests+"'/><br/><br/>");
            out.println("<input type='submit' value='Add people'/>");
            out.println("</form>");
            out.println("</body>");
            out.println("</html>");

        }
    }

HttpServlet 必须有Method: doGet,doPost,如果你只想用一个方法的话可以在你的代码里面增加:public void doPost(HttpServletRequest request,HttpServletResponse response) {
//业务逻辑
}public void doGet(HttpServletRequest request,HttpServletResponse response) {
doPost(request,response);
}

同楼上意见，也可以把请求改成method="get"

他虽然可以只写doGet/doPost,但是除非你完全能够明白你用什么方式来提交,否则最好像我写的那样.
HTTP method POST is not supported by this URL 从错误提示里推测,你页面提交时，URL是错的。可以再写一个form类，并写在：
out.println(" <form action='add_people.do' name='formFoullName' method='POST'>");

我同样的正常运行的练习，这个servelt里就一个doPost()...（原理一样的练习）

你在servlet里把那个请求URL打印出来看看,或者看看浏览器窗口中的URL,贴出来看看

http://localhost:8084/Jw1/admin/add_people.do

.do ???????????你哪学的啊.jsp试试

调试易
