Connecting through a proxy WSAD / BorderManager / JSSE

I am trying to get the InputStream from a URLConnection object. The connection must be established with the Internet through a proxy.

My code stops at the following line: line = reader.readLine();

I already asked my security guys if I could tunnel through and they change the setting on the proxy server to allow for HTTP tunelling and they said no because it is a security risk.

Here is my environment:
IBM WebSphere Application Developer 4.03 w/ JDK 1.3.1
Proxy Server: Novell Border Manager
I have jecert.jar, jnet.jar and jsse.jar in my classpath and they are located here: C:\Program Files\IBM\Application Developer\jre\lib\ext
(I was told I need to use the SUN classes and not the IBM ones)

From my java.security file:
security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.net.ssl.internal.ssl.Provider
security.provider.3=com.ibm.crypto.provider.IBMJCA

Here is my code:

Code:

package com.MattSidesinger.test;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
import java.security.Security;

import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;

public class ProxyConnectionTester
{

	public static void main(String[] args)
	{
		try
		{
			// Set the system and security properties
			System.setProperty("javax.net.ssl.trustStore", "C:\\cacerts1");
		    	System.setProperty("javax.net.ssl.trustStorePassword", "password");

		    	// Keystore location and password	
	     		System.setProperty("javax.net.ssl.keyStore", "C:\\cacerts1");
		    	System.setProperty("javax.net.ssl.keyStorePassword", "password");
		    	
			System.setProperty("proxyHost","bmserver");
			System.setProperty("proxyPort","8080");
			System.setProperty("proxyUserName","username");
			System.setProperty("proxyPassword","password");
			System.setProperty("proxySet","true");
			System.setProperty("http.proxyHost","bmserver");
			System.setProperty("http.proxyPort","8080");
			System.setProperty("http.proxyUserName","username");
			System.setProperty("http.proxyPassword","password");
			System.setProperty("http.proxySet","true");
			System.setProperty("https.proxyHost","bmserver");
			System.setProperty("https.proxyPort","8080");
			System.setProperty("https.proxyUserName","username");
			System.setProperty("https.proxyPassword","password");
			System.setProperty("https.proxySet","true");
   		    	System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
		    	
			Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
			
			// connect to get the web page
			URL url = new URL("http://www.google.com");
			URLConnection connection = url.openConnection();
						
			// get the contents of the web page
			InputStream stream = connection.getInputStream();
			BufferedReader reader = new BufferedReader(new InputStreamReader(stream));

			// read in the entire web page
			StringBuffer webPage = new StringBuffer();
			String line = null;
			
			while(true)
			{
				line = reader.readLine(); // STOPS HERE
				if (line == null)
				{
					break;
				}
				webPage = webPage.append(line);
			}
								
			// close all resources that we do not need
			// now that the web page has been obtained			
			stream.close();
			reader.close();
			
		}
		catch (MalformedURLException e)
		{
			System.out.println("MalformedURLException");
		}
		catch (IOException e)
		{
			System.out.println(e.toString());		
		}
	}
}

There were no errors when I installed the certificates to the keystore using the keytool.

I will keep you updated if I have any further advances.
