Accessing data over HTTP

I am attempting to get information from an asp page on a separate server with java.

Here is what I am currently running for code:

<%@ page contentType="text/html;charset=UTF-8"%>
<%@ page import="java.util.*" %>
<%@ page import="java.text.*" %>
<%@ page import="java.net.*" %>
<%@ page import="java.io.*" %>
<%@ page import="com.nse.common.text.*" %>
<%@ page import="com.nse.common.admin.*" %>
<%@ page import="com.nse.common.util.*" %>
<%@ page import="com.nse.common.config.*" %>
<%@ page import="com.nse.ms.*" %>
<%

        String targetUrl = "http://******/dash_auth/getmsuser.asp";
        InputStream r2 = new URL(targetUrl).openStream();

%>

<html>
<head>
    <title>get username</title>
</head>

<body>
Return Info = <%=r2%>
</body>
</html>

And this is what I am getting back

Return Info = sun.net.www.protocol.http.HttpURLConnection$HttpInputStream@5fc9f555

I am hoping to get a username back and not this connection string. Any suggestions on how to get the actual output of my other page would be very helpful!

You need to use an http client to create a connection and get the content back. Or make a system call to a OS utility like curl.

Here is a sample on how to use the http Client

http://hc.apache.org/httpclient-legacy/tutorial.html

If you want to do it in an unmanaged way, this is a working example:

public class URLStreamExample {

public static void main(String[] args) {
    try {
        URL url = new URL("http://www.google.com");
        InputStream is = url.openStream();
        byte[] buffer = new byte[2048];
        StringBuilder sb = new StringBuilder();
        while (is.read(buffer) != -1){
            sb.append(new String(buffer));
        }

        System.out.println(sb.toString());
    } catch (MalformedURLException e) {
        e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
    } catch (IOException e) {
        e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
    }
}

}
