The security tutorial mentions that I need to use the jboss annotation org.jboss.ejb3.security.SecurityDomain, but it doesn't seem to exist in the jars that come with 4.2.3. I added all the jars in the jboss lib directory to my external library, but still don't have access to this class. Is there another jar file I need? Thanks again for the help.
