Add the following annotation: @SecurityDomain("exemplo1") | public class UserManagementBean implements UserManagement { | .... | } to your bean so that the security domain is set. Even your manual modification to the jboss.xml should have worked. Are you sure that you have correctly added the security-domain to the jboss.xml (make sure you have not made any spelling mistakes about the security-domain name)? Looking at the stacktrace instead of picking up "exemplo1" its picking up "other" (which uses UsersRolesLoginModule) from the login-config.xml View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3976001#...
