Hi, I have a problem with JBoss security. I implemented an interceptor in which I need to read the current principal. This basically works very well, I get the subject using the following code: 1. (Subject) PolicyContext.getContext("javax.security.auth.Subject.container") The problem occurs when I have a Message Driven Bean which is annotated with @RunAs("SYSTEM"). The code above always returns null. I also tried the following code, to read the subject. Subject.getSubject(AccessController.getContext()); and also reading from the sessionContext sctx.getCallerPrincipal() With all this, I didn't have success. I saw in the JBoss sources that the RunAsIdentity is sort of a special treatment which is read by the SecurityInterceptor like this: SecurityActions.peekRunAsIdentity() But calling this is not possible for me due to security restricitons and I think it's also not meant to be read like this. Does anybody have an idea what is the correct way to read the subject and principal in this case?
