I am trying to display a jsp page which contains user image and user information.
Here is the JSP code:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<%@page import="utils.MyUtils"%>
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%
Connection con = MyUtils.getStoredConnection(request);
String strSQL = "SELECT IMAGE "
+ "FROM CUSTOMER "
+ "WHERE CUST_ID= 111";
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(strSQL);
rs.next();
out.clear();
OutputStream os = response.getOutputStream();
String hello = "Hello";
os.write(hello.getBytes());
response.setHeader("expires", "0");
response.setContentType("image/jpeg");
os.write(rs.getBytes("IMAGE"));
out.flush();
%>
Here is my servlet:
package servlet;
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;
import javax.servlet.http.HttpSession;
import beans.UserAccount;
import utils.MyUtils;
@WebServlet(urlPatterns = { "/userInfo" })
public class UserInfoServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public UserInfoServlet() {
super();
}
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
HttpSession session = request.getSession();
// Check User has logged on
UserAccount loginedUser = MyUtils.getLoginedUser(session);
// Not logged in
if (loginedUser == null) {
// Redirect to login page.
response.sendRedirect(request.getContextPath() + "/login");
return;
}
// Store info to the request attribute before forwarding.
request.setAttribute("user", loginedUser);
// If the user has logged in, then forward to the page
// /WEB-INF/views/userInfoView.jsp
RequestDispatcher dispatcher //
= this.getServletContext().getRequestDispatcher("/WEB-INF/views/userInfoView.jsp");
dispatcher.forward(request, response);
}
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
But when i run my code the page only contains image and it doesn't show any information (Here i tried to print "Hello" in the page as information). What should i do? The images are stored in my PC.
