        • 1. Re: Could not instantiate Seam component: authenticator
          Olivier Thierry Apprentice

          It might be a problem with jta-datasource tag in your persistence.xml file. Are you sure about java:/seamDemoDatasource value ? In my config file, it starts with java:/jdbc, so it should be java:/jdbc/seamDemoDatasource in your case.

              Daniel Hinojosa Master

              I don't think you needed to do that.
              Do you actually have java:/seamDemoDatasource deployed first of all?


              You can check when you start up JBoss it will typically state that it has loaded
              Also, are you using seam-gen or your own folder format?


              Let us know

                  So when you deploy your app, without going to any page, are there any other error or warning messages?

                    Hi Daniel Hinojosa,

                               I solved the problem,i made a small mistake i.e my components.xml file is
                    --
                    <persistence:managed-persistence-context name="entityManager"
                                                         auto-create="true"
                                              entity-manager-factory="#{seamDemoEntityManagerFactory}"/>
                    ----
                    -
                    so,i changed

                    @In
                    private EntityManager entityManager;(before entityManager is em)
                    and removed the @Statefull annotation.
                                     
                    Thank you Daniel Hinojosa.

                      Ah, also I don't think the @Stateful annotation has anything to do with it.  I think you can have a @Stateful authenticator you would just need to provide Local and Remote interfaces for it. I could be wrong since I have never have tried it.  But I am glad that worked out for you.  ;)
