    EJB Async

    paul.setzermann Newbie



      I tried the EJB Asynchronous annotation but it is not working!

      I thought 7.0.2 is supporting it.

      Maybe I am missing something!?

      Could someone give me a short example?

          Can you be a bit more precise how it is not working for you?

          Do you get an exception?

          Is the invocation synchronous? If so, how did you verify?

            The method is invoked synchronously.

            When I check the a4j:log it´s always waiting for the asynch method to complete.

            My code looks like this:



             <a4j:commandButton action="#{updateAdbBean.update()}" value="Start" execute="@form" />
            public class UpdateAdbBean implements Serializable {
                      private static final long serialVersionUID = 2778548975359198879L;
                      public void update() {
                                          FillOrUpdateAdbManager fillOrUpdateAdbManager = lookup(FillOrUpdateAdbManager.class);
                                          fillOrUpdateAdbManager.fillOrUpdate(true, updateAdbView.getSource(), adbSpecies, progressBean);
            public class FillOrUpdateAdbManager {
                      public void fillOrUpdate(boolean bUpdate, String source, ADBSpecies species, ProgressBean progressBean) {
                                try {
                                } catch (InterruptedException e) {


            Thanks and Cheers,

              I ve same problem


              The code is synchronous, not asynchronous






              public class AsyncBean {


                  public void ignoreResult(int a, int b) {


                            try {


                                  } catch (InterruptedException e) {

                                            // TODO Auto-generated catch block



                            System.out.println("fin sleep");

                      // the client doesn't care what happens here

                jboss 7.0.2 supports only ejb 3.1 light which do not have the asynch call as you can see here http://www.theserverside.com/news/1321142/Part-Three-New-Features-in-EJB-31 (look at the table... Table 1: EJB and EJB Lite Feature Comparison)


                look also here




                where you can find the profile's stack both for specs and for jb 7.0.x

                  Hey Riccardo,


                  Thanks for your help, but why is this stated in the release information?



                  ANKÜNDIGUNG: AS 7.0.2.Final "Arc" released!

                  A month after 7.0.1.Final was released, we now have  7.0.2! The binary downloads are available here. 7.0.2 "Arc" is mainly a bug fix release but also brings some new features and improvments:

                  • JSF 2.1
                  • Async EJB support!!
                  • Resurrected -b option for command line binding
                  • SSO support
                  • JNDI memory footprint improvement
                  • Limited support for Hibernate 3.3

                    Can you add some println statements to both UpdateAdbBean.update and FillOrUpdateAdbManager.fillOrUpdate?

                    Specifically: System.err.println(Thread.currentThread());

                    also add: new Exception("here").printStackTrace(); to fillOrUpdate.


                    It should show two different threads and a trace which is running in the asynchronous executor service.

                      maybe a documental bug or in the RN or in the user guide... it's hard to think a bug in the specifications... they are specifications and they say no async call for ejb light...


                      with the distribution you should have the *-preview.xml which is the full jee stack (as far as i've understood), so we can assume a bug in the user guide (no ejb light in the full stack but full ejb)


                      so try with that standalone/domain configuration


                      and share

                        Hi, are you telling us that the jboss implementation of ejb light supports async calls?

                          No, good catch.


                          The default configuration is only lite enabled:

                          <subsystem xmlns="urn:jboss:domain:ejb3:1.1" lite="true">

                          Which in turn does not have async support.



                          $ ./standalone.sh --server-config standalone-preview.xml

                            The announcement in this forum has now been edited to make it a bit more clear that the async EJB support is available in the standalone-preview configuration of "everything" distribution.
