I registered my AuthConfigProvider programmatically inside a ServletContextListener.
I can see it using the little WAR provided by Shing Wai Chan [1]. I made a screenshot and attached it to this post.
Now my problem is that my AuthConfigProvider is never called when I issue a request on a servlet from the "zeng-war" application.
With some work I could provide Netbeans projects to test this out. Will you be interested ?
