    Scheduling in Seam?

    Devon Hillard Novice

      I have a seam component which has a method I would like to invoke on a scheduled basis. All the jboss scheduler docs I can find seem to say the scheduled code has to be deployed in a .sar.

      1) I'd really like to avoid having to put a .sar next to my .jar and .war just for one class.

      2) I'm not even sure if I could make seam lookups/calls between my .jar and .sar... right?

      Any suggestions on how I can get my code called on a schedule?

      Regards,

      Modoc

          You mean using Seam 1.1 @Asynchronous methods? You don't need a sar...

            I hadn't seen that. I was referring to the normal jboss scheduler.

            I will checkout the @Asynchronous...

            Thanks!

              in Chapter 13, it refers to the IntervalDuration as a long (millis I assume?):

              @Asynchronous public Timer scheduleAlerts(Alert alert, @Expiration Date date, @IntervalDuration long interval) { ... }


              But in Chapter 7, it refers to it as a Date:

              @Asynchronous
              public void processRecurringPayment(Payment payment, @Expiration Date date, @IntervalDuration Date interval)'


              A long doesn't seem to work, and the seam source java comments refer to a Date, however, it doesn't make any sense to me to measure an interval with a date... A date is a fixed date, not a duration or interval. If I am supposed to use a date, how do I create a date for one minute?

              Thanks!

                It should be a long. The JavaDoc is wrong.

                  Ok. So the javadoc and chapter 7 are wrong. I still can't get it to work with a long. I've tried on the assumption that it's millis and then when that didn't work seconds.

                  I may be doing something wrong. There aren't any examples of it that I can find.

                  Here's my code:

                  @Asynchronous
                   public void processEmailsRecurring(@Expiration
                   Date pDate, @IntervalDuration
                   long pInterval) {
                   mLog.info("proccessEmailsReccurring running...");
                   processNewEmails(mIMAPClient.getNewMessages());
                   }
                  


                  Which gets called by:


                  @Create
                   public void doStartService() {
                   mLog.info("Starting up...");
                   mLog.info("Kicking off recurring email processor.");
                   processEmailsRecurring(new Date(), 2);
                   }
                  


                  I've tried with 2 and with 60000.

                  Either way, it starts up, calls the method, which runs once, and never runs again:

                  22:25:17,277 INFO [EmailManager] Starting up...
                  22:25:17,277 INFO [EmailManager] Kicking off recurring email processor.
                  22:25:17,277 INFO [EmailManager] proccessEmailsReccurring running...
                  


                  Any ideas what I'm doing wrong?

                  Thanks!

                    Ok. So the javadoc and chapter 7 are wrong.



                    Really?

                    But chapter 7 clearly tells you to put the @Asynchronous annotation on the local interface, not on the bean class.

                    And yours is on the bean class.

                      What I meant when I said chapter 7 is wrong, is that chapter 7 says that IntervalDuration is a Date not a long. Chapter 13 is the only place where the IntervalDuration is referred to as a long.

                      Chapter 7 also clearly says:

                      (For JavaBean components we can annotate the component implementation class if we like.)


                      And since this component is a POJO, I put the annotations on the implementation class.

                      Is this wrong? Do Ansyncronous annotated methods HAVE to be ejbs? If so, that's fine, I'll make an ejb interface/impl pair just to handle this, but the documentation led me to believe I could annotate a javabean component.

                      Because it felt to me that your reply was a little defensive or sarcastic, I want to assure you that I am in no way implying any failings of Seam, its documentation, examples, or your work on it. I've worked on plenty of projects to know that keeping docs, examples, javadoc, etc... all in sync with a changing product is hard to do without a dedicated doc team. Seam seems like a pretty amazing project, and thus far I'm really impressed by it. All I'm trying to do it figure out how to get my project working, and at the moment my lack of familiarity with Seam and the ejb3 spec, combined with a couple doc issues and the fact that since Seam is so new, there aren't a ton of other sites with information other developers have uncovered, I come here to ask my questions.

                        OK, np, ....


                        (1) Can you show me your code (all of it)
                        (2) What environment are you running in (JBoss with EJB3?)


                        I'm not trying to say there are no bugs in this stuff (no doubt there are) or in the docs (I know there are). But lets take it a bit more slowly and patiently, please.

                        Cheers.

                            The problem is that you are calling the @Asynchronous method from another method of the class. Calls to this do not get intercepted by the EJB container (or by Seam). You need to call the method from another component if you want it to be processed asynchronously.

                              Or you move the method to a different component and call it from the original component. Maybe this also could be handled in a inner class? Or am I saying stupid things now?

                                Ok good to know. I didn't know that about intercepting stuff. However, I'm now having errors. here are the two new classes, and the error messages I get at startup. I would greatly appreciate any insight into what I'm doing wrong.

                                  Show me your startup log, I want to see if "org.jboss.seam.core.dispatcher" gets installed. (Looks like it does not.)

                                    Oh, I think I forgot to document that you need to install the dispatcher using:

                                    <component name="org.jboss.seam.core.dispatcher"
                                     class="org.jboss.seam.core.Dispatcher" />


                                    in components.xml.

                                    Sorry about that.

                                    I'll also make the NPE look prettier.
