I am attempting to connect to a local proxy to inspect my internet trafic.

The proxy is listening to port 8888 so I though the attached code would
pass through it and I would the see request/response.  Nothing happens in
the
proxy.

Java seems to be ignoring the proxySet stuff.  I would have been happy just
to
get an error code something like invalid port

I attempted setting these parameters with the java -D
java -DproxySet=true -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=8888

Thanks for any suggestions

code example

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

class ProxyTest {

public static void main(String [] args) {
 System.getProperties().put( "proxySet", "true" );
 System.getProperties().put( "http.proxySet", "true" );  //probably not
needed
 System.getProperties().put( "http.proxyHost", "ggcdell" );  // name of my
computer
 System.getProperties().put( "http.proxyPort", "8888" );
     String ht = "http://csmerge.cira.colostate.edu";
     try {
        URL url = new URL(ht);
  URLConnection conn = url.openConnection();
        conn.connect();
        DataInputStream s = new DataInputStream(conn.getInputStream());
        String line = s.readLine();
        while (line != null) {
           System.out.println(line);
           line = s.readLine();
        }
        s.close();
     } catch (Exception ee) {
        System.out.println(" should arrive here ");
        ee.printStackTrace(System.out);
     }
  }
}
