What's the problem of this program

[tester]

Hello, I am writing a java application to get a file from a HTTPS web
server.
The code is shown below. I have installed JSSE in advance (btw, is there
any
way to check whether the JSSE is installed successfully or not?). But I
got
ConnectException:Connection timed out error. Do u have any idea of the
reason?

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

public class TEST
{
public static void main (String args[]) throws Exception
{
System.getProperties().put("proxySet", "true");
System.getProperties().put("proxyHost", "PROXYSERVER");
System.getProperties().put("proxyPort", "8000");
System.setProperty("java.protocol.handler.pkgs",
"com.sun.net.ssl.internal.w
ww.protocol");
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
URL url = new URL("https://XXX.com/YYY.txt");
BufferedReader br = new BufferedReader(new
InputStreamReader(url.openStream()));

String line;
while ((line = br.readLine()) != null)
{
System.out.println(line);
}
br.close();
}
}

Well, for one thing, you can't set system properties that way. It does
nothing. You can set them on the java command line, or (IIRC) in the
appropriate configuration file.

Well blow me down. Okay, I checked and you're right, with the caveat
that a security manager can prevent the retrieval of the Properties
object. I don't know what I was thinking.
