@EJB injection not working in JBoss 6.x

gunterze Aug 30, 2011 9:49 AM

I tried to use @EJB annotation in MC bean in JBoss AS 6.x to inject SLSB, but without success. There is no error log, the annotated field just remains null. Doing the JNDI lookup manually works. Have I activate the EjbReferenceAnnotationPlugin in some way?

Thanks,

gunter

Hi Gunter,

I'm not sure if this is your issue, but when I forget to add a META-INF/beans.xml I get the same behaviour. No error and the injected resource in null as I believe WELD will not pick up the deployment and hence not scanning it for annotations.

Regards,

I think this is a diff issue; Weld != MC. ;-)

Did you follow ALR's instructions on how to do this?

I thought ALR's solution with

org.jboss.ejb3.mcint.metadata.plugins.EjbReferenceAnnotationPlugin
org.jboss.ejb3.mcint.metadata.plugins.AbstractEjbReferenceValueMetadata
org.jboss.ejb3.mcint.annotationadaptor.AddAnnotationPluginOnBeanAnnotationAdaptorCallbackService

is already included in JBoss 6.x and deployed by jboss-6.1.0.Final/server/default/deployers/ejb3.deployer/META-INF/ejb3-deployers-jboss-beans.xml:


<bean name="org.jboss.ejb3.AddAnnotationPluginOnBeanAnnotationAdaptorCallbackService"
    class="org.jboss.ejb3.mcint.annotationadaptor.AddAnnotationPluginOnBeanAnnotationAdaptorCallbackService">
    <constructor>
      <parameter><inject bean="jboss.kernel:service=Kernel"/></parameter>
    </constructor>
</bean>



<bean name="org.jboss.ejb3.EjbReferenceAnnotationPlugin"
    class="org.jboss.ejb3.mcint.metadata.plugins.EjbReferenceAnnotationPlugin">
    <constructor>
      <parameter><inject bean="org.jboss.ejb3.EjbReferenceResolver" /></parameter>
    </constructor>
</bean>

by default. Isn't it?

Oops, I missed your comment at http://exitcondition.alrubinger.com/2008/12/20/doing-two-models-at-the-same-time/ :

Perhaps a missing detail that gave you problems as well is the no-fields by default.
Meaning one must change BeanAccessMode –> FIELDS or ALL.

Adding
<bean .. access-mode="ALL">
and it works as expected. Thanks!
