Question

我正在使用java servlet来获取表单值并显示它。我已完成其他人针对此问题发布的所有更改。但我仍然得到这个错误。

这是我的servlet：

@WebServlet("/UpdateDetails")
    public class updateDetails extends HttpServlet 
    {    
       protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException 
       {
          <br/>
          String name=request.getParameter("appName");<br/>
          System.out.println(name);

          PrintWriter writer = response.getWriter();

          // build HTML code
          String htmlRespone = "<html>";
          htmlRespone += "<h2>Application: " + name + "<br/>";
          htmlRespone += "</html>";

          // return response
          writer.println(htmlRespone);
       }
}

HTML

<form name="edit" action="UpdateDetails">

我收到404错误
