我在servlet中收到ping结果,试图将其重定向到另一个jsp文件。
将打开用于输出的jsp文件,但其中没有任何显示。
这是我的servlet主要代码
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated method stub String ip = request.getParameter("ip"); response.setContentType("text/html"); PrintWriter out = response.getWriter(); // out.println("The ip address is:"+ip+"\n"); String result = pingTest(ip); out.println(result); String redirect = "Output.jsp"; RequestDispatcher view = request.getRequestDispatcher(redirect);//Is it good approach to redirect request in ajax based servlet? view.forward(request, response); }
这是我的output.jsp页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Ping Check Result</title> </head> <body> </body> </html
我是否需要在output.jsp中添加任何内容?
在您的servlet中:
request.setAttribute("result", result); request.getRequestDispatcher("/WEB-INF/Output.jsp").forward(request, response);
在您的JSP中:
<pre>The data from servlet: ${result}</pre>
