I try to send a short text from a servlet to a jsp, and display the text on the jsp page. But on the jsp page I see "null".
I have a jsp file: show.jsp :
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<title>Insert title here</title>
</head>
<body>
Here is some text
<%
Object message=request.getAttribute("message");
out.println(message);
%>
</body>
<%= request.getAttribute("message") %>
</html>
And I have a servlet: DataServlet.java :
package com.servlettojsp;
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/DataServlet")
public class DataServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public DataServlet() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String mes="This is a message from the servlet";
request.setAttribute("message", mes);
RequestDispatcher rd= request.getRequestDispatcher("show.jsp");
rd.forward(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
}
Why I can't pass data from servlet to jsp ?
