Hi all! I have a problem when I authenticate the user. I use JBoss-4.0.5.GA, EJB3.0. I use the DatabaseServerLoginModule to authenticate a user. Here, I only test isCallerInRole method to receive true or false. The first, when I run my app (example: username is Jack that has role is doctor and nurse): | ..... | LoginContext lc = new LoginContext("client-login", new DefaultCallbackHandler()); | lc.login(); | Methods mth = (Methods)ctx.lookup("MethodsBean/remote"); | boolean t = mth.callerIsRole("doctor"); | System.out.println(t); ----> t=true !! (JBoss server print "True") | lc.logout(); After, I edit database in mySQL(delete a role doctor). And run my app abow, but Jboss server still print "True" ---> (I think after I call lc.logout(), JBoss will remove principals of user Jack.). Please help me !!!
