Custom authentication provider calling a web service

Hi all,

I am currently working on a custom authentication provider for WebLogic as written here:| Basically when our users log in, the credentials get validated by calling a web service and based on the response of that, the user might be able access our webapplication or not.

I started by writing my AuthenticationProvider and LoginModule class, without including the web service call for now, and afterwards packaged it into a jar to deploy it to WebLogic. Everything seemed to work fine so I included the web service call to the LoginModule's login()-method. However, after doing so I noticed that everytime the web service is about to get called, the rest of my method is being skipped, he just jumps out of my class. I assume something went wrong while calling the service although I don't get any Exception at all, he just proceeds to the next authentication provider.

I tested the web service in a separate testclass and it does work. So my question is whether it's uberhaupt possible to call a web service during the authentication process?


Edit: I've started to notice that the problem occurs when he's fetching the Port of the web service. As a test i've located a test webservice call (basically it just instantiates a webservice, gets the port and performs a method) in my AuthenticationProvider's initialize()-method. It seems to fail at the exact same moment as when I called the web service in my LoginModule, although now i'm getting an Exception: "java.lang.IllegalArgumentException: interface is not visible from class loader". The code it's trying to run is:

I agree. Here's the link:
