I am running the following java program in the Eclipse IDE:
import java.net.*;
import java.io.*;
public class HH
{
public static void main(String[] args) throws Exception
{
//if i comment out the system properties, and don't set any jvm arguments, the program runs and prints out the html fine.
System.setProperty("http.proxyHost", "localhost");
System.setProperty("http.proxyPort", "8888");
System.setProperty("https.proxyHost", "localhost");
System.setProperty("https.proxyPort", "8888");
URL x = new URL("https://www.google.com");
HttpURLConnection hc = (HttpURLConnection)x.openConnection();
hc.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 6.0)
AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2");
InputStream is = hc.getInputStream();
int u = 0;
byte[] kj = new byte[1024];
while((u = is.read(kj)) != -1)
{
System.out.write(kj,0,u);
}
is.close();
}
}
This produces the following exception, if fiddler is RUNNING, both while capturing, and not capturing:

If I close fiddler, the program runs fine without any exceptions, producing the html on the url i am connecting to.
alternatively, if i specify System.setProperty("https.proxyPort", "443");
, instead of: System.setProperty("https.proxyPort", "8888");
, it runs and prints out all html, without exceptions, even while fiddler is open, in capturing mode, but there is still no capturing from fiddler at all.
Then if I set these system properties through eclipse's jvm arguments like: -DproxySet=true -DproxyHost=127.0.0.1 -DproxyPort=8888
, the same exact exception happens again, so long as the fiddler app is running, both in capturing and non capturing mode. If i close fiddler, the program will run perfectly fine.
If i use: System.setProperty("http.proxyHost", "127.0.0.1");
instead of: System.setProperty("http.proxyHost", "localhost");
, it runs fine with fiddler application running, both cap-/non capturing mode, but also NO captured traffic.
Is anyone out there, able to capture their own https traffic with fiddler, NOT through a web browser, but through a java program? What are the jvm arguments, how do you set it up to do this? thanks
