  • 0

I’ve a query regarding JAVA (Reading directly from the URLs). I want to read the contents from URLs. I’ve just implemented a code in JAVA and it works well. But i want that code to be implemented in JSP. I tried to use this on JSP page but it does not read the contents of the URL. Please help me out.

JAVA CODE

import java.net.*;
import java.io.*;

public class URLReader {
    public static void main(String[] args) throws Exception {

        URL oracle = new URL("http://www.oracle.com/");
        BufferedReader in = new BufferedReader(
        new InputStreamReader(oracle.openStream()));

        String inputLine;
        while ((inputLine = in.readLine()) != null)
            System.out.println(inputLine);
        in.close();
    }
}

JSP CODE

<%@ page import="java.sql.*,java.net.*,java.io.*,java.lang.*,java.util.*"%>
<html>
<title></title>
<head></head>
<body>

<%
try{
    URL oracle = new URL("http://www.oracle.com/");
    BufferedReader in = new BufferedReader(
    new InputStreamReader(oracle.openStream()));

    String inputLine;
    while ((inputLine = in.readLine()) != null)
        System.out.println(inputLine);
    in.close();
    }catch(Exception ex){}
%>
</body>
</html>

I’m using JDK1.5.0_16 and Tomcat Version 3.0

    Your mistake in JSP is the following line:

    System.out.println(inputLine);

    This prints the line to the stdout (the console, logfile, etc), not to the HTTP response.

    Use the implicit out object referring the response output stream:

    out.println(inputLine);

    Or, better, just use JSTL <c:import>. Scriptlets are namely discouraged since a decade. 

    <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
...
<c:import url="http://www.oracle.com" />

    Don’t forget to upgrade your ancient (that was a understatement…) server first. Given that you’re fiddling with JSPs the oldschool way, I’d also wonder if you’re reading the
    right and up-to-date resources while learning JSP.
