set proxy host/port ???

[G. Garrett Campbell]

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);
}
}
}

What response are you getting?

I do not get any error message, just the contents of the web site.
That appears wether I have the proxy turned on or off.

Try

System.getProperties().put( "proxySet", "true" );
System.getProperties().put( "proxyHost", "ggcdell" );
System.getProperties().put( "proxyPort", "8888" );

Note no http. at the begining of the settings.

Java seems to be ignoring the proxySet stuff.

It does. See below.

I would have been happy just

System.getProperties().put( "proxySet", "true" );
System.getProperties().put( "http.proxySet", "true" );

Neither of these has any effect whether set to 'true' or 'false'. Urban
legend (and several books) notwithstanding, there are no such properties
in Java and never have been. They were defined for the shortlived
HotJavaBean which lived and died around 1998.

 

[Esmond Pitt]

System.getProperties().put( "proxyHost", "ggcdell" );
System.getProperties().put( "proxyPort", "8888" );

Note no http. at the begining of the settings.

Don't expect any change from doing this. These are just synonyms for the
http.* names, which are preferred and should be used.

See my other posting. You can't turn it off, except by deleting
http.proxyHost/proxyPort. If it works when you set these properties,
your proxy is working. Isn't that what you expect?

 

[G. Garrett Campbell]

I got the following to work

System.getProperties().put( "proxySet", "true" );
System.getProperties().put( "http.proxyHost", "127.0.0.1" ); // name of
my computer
System.getProperties().put( "http.proxyPort", "8888" );

 

[Esmond Pitt]

I got the following to work

System.getProperties().put( "proxySet", "true" );

OK so try that with 'false' and tell us what difference it makes. My
prediction: zero.
