    Call EJB Jar from MBean inside sar

    Anurag Bhatia Newbie

      I am trying to call an ejb method from inside the start() method of an mbean which is inside a sar.

      The depends tag has been placed inside the jboss-service.xml. But the lookup always fails - NameNotFoundException - env not bound.

       

      How do I lookup the ejb session bean from the mbean? Do I need additional configurations?

          Can't say much without looking at the exception stacktrace and the configuration files.

            The jboss-service.xml is defined as follows -

             

            <server>

              <mbean code="com.registration.Registration" name="registration.mbeans..com:service=Registration">

              <depends>jboss.j2ee:jndiName=com/ejb/configuration/ConfigurationLocal,service=EJB</depends>

              </mbean>

            </server>

             

            The jar containing the EJB and the SAR is deployed in one ear file.

            The start method of the mbean invokes a POJO method which in turn calls an EJB methof

             

            The stack trace -

              Also, if I invoke the start() method of the MBean from the JMX console after the server has started; the lookup works without any exceptions.

                </server>

                That's an incorrect value in the <depends>. The value should be of the form:

                 

                <depends>jboss.j2ee:ear=YourEARName.ear,jar=YourEJBJarName.jar,name=YourBeanName,service=EJB3</depends>
                

                 

                If the bean is deployed in a standalone jar instead of a ear, then the JMX ObjectName will not the the ear=xyz key/value:

                 

                <depends>jboss.j2ee:jar=YourEJBJarName.jar,name=YourBeanName,service=EJB3</depends>

                  After posting my previous reply, I now see that you have tagged your question with "JBoss AS 4.2". So what version of JBoss AS are you using and what version of EJB? EJB2.x or EJB3?

                    Bumping old thread

                     

                    I have tried to use this syntax in AS 7.1.1 Final and it seems doesn't work. Is this feature not supported anymore?

                     

                    Here is fragment of my jboss-service.xml

                     


                    <mbean code="com.supportwizard.seance.registry.SeanceRegistry" name="supportwizard:service=seanceregistry">
                      <depends>jboss.j2ee:jar=SWSeance-ejb.jar,name=SeanceE,service=EJB3</depends>

                     

                    In log I see:

                     

                    23:21:39,142 ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) {"JBAS014653: Composite operation failed and was rolled back.

                    However bean was deployed 10 seconds earlier:

                     

                    23:21:29,251 INFO  [org.jboss.as.ejb3.deployment.processors.EjbJndiBindingsDeploymentUnitProcessor] (MSC service thread 1-15) JNDI bindings for session bean named SeanceE in deployment unit deployment "SWSeance-ejb.jar" are as follows:

                    I looked at sources and cannot understand how it supposed to work. It looks like only optional-attribute counts:

                     

                    public class ParsedServiceDeploymentProcessor implements DeploymentUnitProcessor {

                    ...

                    final JBossServiceDependencyConfig[] dependencyConfigs = mBeanConfig.getDependencyConfigs();

                    if (dependencyConfigs != null) {

                         final Service<Object> createDestroyService = mBeanServices.getCreateDestroyService();

                         for (final JBossServiceDependencyConfig dependencyConfig : dependencyConfigs) {

                              final Injector<Object> injector = getInjector(dependencyConfig, mBeanClassHierarchy, createDestroyService);

                              mBeanServices.addDependency(dependencyConfig.getDependencyName(), injector);

                         }

                    }

                    ...

                    private static Injector<Object> getInjector(final JBossServiceDependencyConfig dependencyConfig, final List<ClassReflectionIndex<?>> mBeanClassHierarchy, final Service<Object> service) {

                         final String attrName = dependencyConfig.getOptionalAttributeName();

                         return attrName != null ? getPropertyInjector(attrName, mBeanClassHierarchy, service, Values.injectedValue()) : NullInjector.getInstance();

                    }

                      I'm having similar issues getting an mbean to depend on and use an ejb (both sar & ejb.jar deployed in the same ear).  Did you ever find an answer?

                        Unfortunately, I did not. I had to modify my design.
