Making a SOAP call through a proxy! Please help!!!

Question

I'm behind a firewall. I've checked most of the posting in the forum and on the Internet. Most get by using the java.net.Authenticator class, and setting default properties such as https.proxyHost, https.proxyUserName, https.proxyPassword etc. I've tried all that!!! Still doesn't work.
Here's the error msg I get:

As you can see it's pretty messy, and I've tried getting around the HTTPS proxy in a variety of methods, but with no results.
Please help.
Rgds,

Hi,
I've just experienced trouble with the same thing and I found that setting the following System properties works fine when I use the Apache Axis 1.0 libraries. Note that it's "proxyUser" and not "proxyUserName".
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", "10.1.1.1");
System.setProperty("http.proxyPort", "80");
System.setProperty("http.proxyUser", "mydomain\\myusername");
System.setProperty("http.proxyPassword", "mypassword");
I can then make HTTP and HTTPS connections and send SOAP messages with no worries.
I'm in an NT environment and hence had to specify the domain as well as the username (and escape the backslash between them) for the proxy to let me through otherwise I got a "407 proxy authentication required" error.
I'm certain this works fine as I've tested it myself.
Hope this helps you out.
Shane.
