Webservice.wsdl and credentials

So I've got a bit of an issue I'm trying to work through. Perhaps some Flex guru could assist?

I have a WebService instance that attempts to load a WSDL file from our JBoss Application Server. If I do something like this:

webService = new WebService();
webService.destination = WebService.DEFAULT_DESTINATION_HTTP;
webService.wsdl = "http://<removed>/services/ApiService?wsdl";
webService.loadWSDL();

everything works fine. The WSDL is loaded successfully and the application can invoke methods against the web service.

The issue is when I need to add some HTTP authentication to the mix:

webService.setCredentials(userName, password);

this line ends up throwing an error stating that credentials are only supported on HTTPS. Ok fair enough, I want to use secure HTTPS anyway!

So then I tried to change it up to this...

webService = new WebService();
webService.destination = WebService.DEFAULT_DESTINATION_HTTPS;
webService.wsdl = "https://<removed>/services/ApiService?wsdl";
webService.setCredentials(userName, password);
webService.loadWSDL();

and now the WebService instance cannot load the WSDL. The error received is:

[FaultEvent fault=[RPC Fault faultString="HTTP request error" faultCode="Server.Error.Request" faultDetail="Unable to load WSDL. If currently online, please verify the URI and/or format of the WSDL (https://<removed>/services/ApiService?wsdl)"] messageId="6905CC5B-5317-C4B3-2D12-84647EE648A7" type=开发者_开发问答"fault" bubbles=false cancelable=true eventPhase=2]

I can reach this URI in the browser just fine and it returns the WSDL as expected.

I am not a Flex guy (learning) but instead a Java developer. I am trying out Flex as a potential client to our system but this has caused me all kinds of grief today. Google doesn't appear to have any quick answers for me and I am a bit stumped.

First question on StackOverflow so hopefully this gets a bite somewhere and helps some other poor Java dev staying late in the office on a Friday night :-)

This seems to be related to your question. We are planning to use https in the future, so I'm curious to know the solution of your problem.
