Hi: I have the exact same issue. What do you put in the user.properties and roles.propertis file, and where do you place them? I am very new to Jboss also, and just trying to get the Oracle datasource password encryption to work, but it keeps failing with principal=null error. I do not know what "principal is"? Can you please help me. I would really appreciate that! Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4163396#...
