HTTS Proxy error 407

Question

Hello all,
I'm trying to connect to a webservice that runs on a HTTPS address. And I'm in a proxy + firewall.
The first thing I tried was the suggested on weblogic documentation:
Proxy p = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyHost, Integer.parseInt(proxyPort)));               
HttpTransportInfo info = new HttpTransportInfo();
info.setProxy(p);
info.setProxyUsername(user.getBytes());
info.setProxyPassword(pass.getBytes());
And I got the exception:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.0 407 Proxy Authentication Required"
I tryed some variations like use HttpsTransportInfo instead of HttpTransportInfo, and set the proxy data through system properties, but everything give me the same error.
There are any other ways to make a authentication with the proxy? like configure something in the virtual machine or anything like that?

May not be an authentication issue. Please go through this link:
http://www.isaserver.org/tutorials/Troubleshooting_ISA_authentication_issues.html
Confusing Authentication problems.
In many instances most people have confused authentication with a service that is explicitly denying them access to the resource.  Please note that if you are denied access to a resource it has nothing to do with authentication but with permissions to the resource.  An authentication issue normally identifies itself with prompt for user credential or with an error message stating that authentication has failed with the server.
A typical error that you will encounter is error 407 Proxy Authentication Required this means that the authentication has been denied because the user has no valid user account in the domain or that the password has been entered incorrectly.  The 401 error however displays an unauthorized error message this mean the user permissions to that resource are denied.  This error message tells you to look at the ISA server rules not at the way the authentication is handled
Authenticate: username.passwords should be right
Authorization: not allowed to access a resource
"The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied." You might have to look at this authorization issue.
