    how to deploy a service pojo depending on ejb timer

    Maria Luisa Della Vedova Newbie

      I’m new to EJB3 and I’ve the following problem.

      I’m using jboss5.eap.

      I have a service POJO (annotated with org.jboss.ejb3.annotation.Depends, org.jboss.ejb3.annotation.Service, javax.ejb.Local:

      @Service

      @Local(MyInterfaceService.class)

      @Depends(“EJB Global JNDI name”)

      public class MyService implements MyInterfaceService {

       

      and I want to access a stateless EJB from the create() method of this Service POJO.

       

            @EJB

            private ITimer myEJBTimer;

      My EJB is a multiple Timer Object using the TimerService object.

       

      Deploying I get the following warning and errors:

      2010-06-23 13:03:04,080 WARN  [org.jboss.injection.EJBRemoteHandler] (main) EJBTHREE-1828: EJBInjectionContainer jboss.j2ee:ear=ear-name.ear,jar=jarname.jar,name=MyService,service=EJB3 is unconfigured, using legacy resolve

      2010-06-23 13:03:04,502 ERROR [org.jboss.system.server.profileservice.ProfileServiceBootstrap] (main) Failed to load profile: Summary of incomplete deployments (SEE PREVIOUS ERRORS FOR DETAILS):

      DEPLOYMENTS MISSING DEPENDENCIES:

        Deployment "jboss.j2ee:ear= ear-name.ear,jar= jarname.jar,name= MyService,service=EJB3" is missing the following dependencies:

          Dependency "<UNKNOWN jboss.j2ee:ear= ear-name.ear,jar= jarname.jar,name= MyService,service=EJB3>" (should be in state "Described", but is actually in state "** UNRESOLVED Demands 'EJB Global JNDI name' **")

      I understand that my stateless EJB will not yet be bound before my Service POJO create method is called.

      I’ve tried several way of writing the annotation, with and without parameters with no success.

      Obviously if I change my code into

                  InitialContext ctx = new InitialContext();

                  myEJBTimer = (ITimer) ctx.lookup("'EJB Global JNDI name' ");

      I have no problems

      My question is: Is it possible to make my code work with annotation?

      Thanks.

          @Depends(“EJB Global JNDI name”)

          The value of @Depends is incorrect. It should be the MBean name of the EJB container on which you want to depend. For example:

           

          @Depends("jboss.j2ee:ear=ear-name.ear,jar=jarname.jar,name=TheTimerBean,service=EJB3")

            I’ve changed the @Depends.annotation as you suggested.

            @Depends("jboss.j2ee:ear=ear-name.ear,jar=jarname.jar,name=TheTimerBean,service=EJB3")

            I still get

            WARN  [EJBRemoteHandler] EJBTHREE-1828: EJBInjectionContainer

            I was wondering if it might depends on

            https://jira.jboss.org/browse/JBPAPP-3834?page=com.atlassian.jirafisheyeplugin%3Afisheye-issuepanel

             

            thanks

              Is it just the WARN message or do you see any error or exception stacktraces?

                  The NullPointerException is coming from your code:

                   

                  Caused by: java.lang.NullPointerException

                          at  MyService.create(MyService.java:39)

                   

                  So you'll have to see what's wrong with line 39 of that class in your application.

                  • 6. Re: how to deploy a service pojo depending on ejb timer
                    Maria Luisa Della Vedova Newbie

                    on line 39 there is a call to the ejb method for the creation of the timer (ctx.getTimerService().createTimer)

                     

                    with the lookup of the EJB the same code give me no problem.

                     

                    @Service

                    @Local(MyInterfaceService.class)

                    @Depends("jboss.j2ee:ear=earname.ear,jar=jarname.jar,name=TheTimerBean,service=EB3")

                    public class MyService implements MyInterfaceService {

                    @EJB

                    private ITimer myEJBTimer;

                     

                    @Override

                    public void create() throws Exception {

                    line 39           myEJBTimer.attiva();

                          }

                     

                    }
