Hi, I am using seam and i made statefulsessionBean a seam component and i am trying to inject that component in other components, Please help me if i am missing some thing important The following is the stateful session bean + seam component: import javax.ejb.Local; | import javax.ejb.Remove; | import javax.ejb.Stateful; | | import org.jboss.seam.annotations.AutoCreate; | import org.jboss.seam.annotations.Create; | import org.jboss.seam.annotations.Destroy; | import org.jboss.seam.annotations.Name; | | @Stateful | @Name("testSessionEjb") | @AutoCreate | @Local(ITestSessionEjb.class) | public class TestSessionEjb implements ITestSessionEjb{ | | @Create | public void test() { | System.out.println("sriama"); | } | | @Destroy | @Remove | public void destroy() { | | } | | } | The following is the Local Inteface | mport javax.ejb.Local; | | @Local | public interface ITestSessionEjb { | | public void test(); | public void destroy(); | } The following is another component where i am injecting: import org.jboss.seam.annotations.In; | import org.jboss.seam.annotations.Logger; | import org.jboss.seam.annotations.Name; | import org.jboss.seam.log.Log; | import org.jboss.seam.security.Identity; | | | @Name("authenticator") | public class Authenticator | { | @Logger Log log; | | @In Identity identity; | | @In TestSessionEjb testSessionEjb; | | public boolean authenticate() | { | log.info("authenticating #0", identity.getUsername()); | //write your authentication logic here, | //return true if the authentication was | //successful, false otherwise | testSessionEjb.test(); | identity.addRole("admin"); | return true; | } | } The following is the exception i am getting: 5:06:02,844 ERROR [SeamLoginModule] Error
