    Seam and Stateful session bean (EJB 3.0)

    Vemula sriramsudheer Newbie

      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 and 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





       import javax.ejb.Local;
      
      @Local
      public interface ITestSessionEjb {
           
           public void test();
           public void destroy();
      }     


      The following is another component to 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:
