    JAAS and ServiceMBean

    marquier Newbie

      In a secured context managed by JAAS, must a JBoss ServiceMBean have to login to access Beans ?

      Even if the service is logged by a LoginContext, I've an error: Principal==null when this service call the method create on the Bean Home after the authentication (succeded). What's the problem ?

      Thanks in advance for your help !

      PS: my application works well by Web after a login form validation !

            Hallo,

            I have also the same problem, my ServiceMbean which uses
            the ClientLogin methode, can not access a secure EJB.
            I get the error password invalid or required, but i have the same code
            as in my sample client and he works.
            If I copy user.properties and roles.properties in my Service.jar main directory I get the error principal=null.
            It seems that the client authentification method is illegal for the Service MBean. I have Testet also some env settings for the login context, but
            no solution.
            The ServiceMBean and the EJBContainer runs both in the MBeanServer as an MBean. And theortical the ServiceMbean can use the ClientloginModule to access the Container, i have read some papers to get a solution. ( I have not found a solution ).
            I think on Jboss start the ServiceMbean is deployed, the same mechanism which enables the EJBSecurity, sets also the service security.
            And so the ClientLogin Method is unaffected, while the Login Context is set by deployment.

            I have tried to program an own MbeanService for a simple socket Protocoladaptor. I send the user,password, and jndiname of the EJB to the MbeanService. I use this parameter to access the EJB via Jaas and Jndi. Is my Adaptor an OutsideJbossClient this works, when I tried to integrate this into Jboss as ServiceMBean it works not.

            This is a simple Application, and I have read some Books ..... but i have
            no way found to call security methods in a ServiceMbean successful.

            I'm interested on some solutions on Ideas.

              I have used the following code and
              tested the login sequenz with an externel ejbclient, the jaas settings
              are correct

              What i have doing wrong, is this constract legal to the JBoss
              architektur ?

              package MBeanServiceAndJaas;

              import org.jboss.system.ServiceMBean;

              public interface ServiceAdaptorMBean extends ServiceMBean{

              return port;
              }

              }

              then i connect to the service via an socket client and transmit the
              username and the password i get the following errors

              from the service :
