Hi I want to create a simple JAAS domain in JBoss 5.1 and use it for my web, and ejb application authentication. Can you please let me know how I can create the realm and how an Application Client Module can be authenticated before it can invoke an EJB method? I know how to annotated the method to be only accessible for an specific role, what I do not know is how the client application can be configured to do the authentication. Thanks.
