    EJB3 call EJB2

    W Eric Newbie

      I try to call an ejb2 from an ejb3.
      It works fine when I fisrt start Jboss and then hot deploy my ejb3
      But I have an error when my jboss first start with ejb3

      Here is my ejb3 code :

      @Stateless(name="ejb/Eproc")
      public class EprocBean implements Eproc {
      
       @EJB(mappedName="ejb/xx/AdminLocal") private AdminLocalHome adminLocalHome;
       private AdminLocal ejbAdmin;
      
       @PostConstruct
       public void initialiserEProcBean() {
      
       ejbAdmin = adminLocalHome.create();
       }
      }

      AdminLocalHome is my ejb2 and is packaging in a different jar (AdminLocalHome => EJB2.jar and EprocBean => Eproc.jar)

      I am using JBOSS 4.2.2 GA

      Here is my error when jboss start :
      13:18:06,124 WARN [Ejb3DescriptorHandler.getContainers(300)] Descriptor based bean has no ejb-class defined: Eproc

      It look like when my ejb3 start, jboss has not yet loaded interfaces classes which are in ejb2.jar.
      I should explain why "java.lang.NoClassDefFoundError: Lcom/xx/interfaces/AdminLocalHome;"

      But how to solve it ?

      Thanks

            Looks like you are deploying these 2 separately in two separate jar files. Any specific need to deploy these independently? The easiest way is to package both these ejb jars in an EAR and deploy that EAR.

              Yes, there are in 2 separate jars because they come from 2 different projects.
              Why do you say me to package them into an ear ?
              What is different using ear ?

                I suspect that since these beans belong to two different jars (applications), the classes are not shared. Having said that, i can't explain why the hot deployment works.

                You can try adding the bean interfaces to the other jar (EprocEjb.jar).

                  It seems to be a great idea ;-(

                  I found another solution : I have renamed my ejb3 jar to "Zebj3.jar". Then it is loaded in last position (after my ejb2 jar) and I get no more error when jboss start...
