Java Applets, Internet Explorer and Fiddler

Question

Wish the latest Java runtimes (1.5 or 1.6) is the applet pluggin suppoed to use the Internet Explorer web stack to download the .jar file? The reason I ask is I can't see the request in Fiddler. More background - I'm trying to troubleshoot this error:

Answer 1

You can configure the JVM to use Fiddler for networking: http://www.fiddler2.com/fiddler/help/hookup.asp#Q-JavaTraffic

Answer 2

// Specify proxy settings
sysProperties.put("proxyHost","myhost");
sysProperties.put("proxyPort","myport");
sysProperties.put("proxySet", "true");

That's great if you know what "myhost" and "myport" are meant to be....

trying it with localhost or 127.0.0.1 still doesn't work for me :-(
