No Spring Bean found in EJB with SpringBeanAutowiringInterceptor - spring

Question

I need some help: I have one EAR-File, containing one WAR-File, one EJB-Jar-File and some "shared" libs:
aopalliance-1.0.jar commons-logging-1.1.1.jar log4j-1.2.16.jar spring-aop-4.0.5.RELEASE.jar spring-beans-4.0.5.RELEASE.jar spring-context-4.0.5.RELEASE.jar spring-context-support-4.0.5.RELEASE.jar spring-core-4.0.5.RELEASE.jar spring-expression-4.0.5.RELEASE.jar
The War File has a Context initializer which find the spring config and loads everything well.
I now want to use another Spring Context for the EJB Jar.
My EJB is defined as
#Stateless(mappedName = "ejb/SpringRocks")
#RemoteHome(com.ibm.websphere.ola.ExecuteHome.class)
#Interceptors(SpringBeanAutowiringInterceptor.class)
public class WolaUseCaseOne {
#Autowired
private DummyService dummyService;
/* ...More stuff here */
Inside the EJB-JAR, there is also a beanRefContext.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="myEjb" name="myEjb" class="org.springframework.context.support.ClassPathXmlApplicationContext">
<constructor-arg value="classpath*:META-INF/spring/simpleEjb.xml" />
</bean>
</beans>
The simpleEjb.xml is is also inside the EJB-Jar and is defining a very simple Bean:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="myDummyService" class="com.provinzial.beispielanwendung.batch.wola.DummyServiceImpl" />
</beans>
As described, the WEB Part works perfect, but when the EJB is called, the SpringBeanAutowiringInterceptor is called, but seems to do nothing. What do I have to do, to get a Spring Context created?! My hope was that it is initialized when the EJB is created. I created a Subclass of SpringBeanAutowiringInterceptor with some loggers, but the class is only created, no method is called !
What else do I have to do? Or does anybody have a valid EAR File example?
I think the Problem is that inside the EJB Module no context is initialized...

I was facing similar issue with my EJB (no WAR). This is what fixed mine,
I was missing the spring-aop jar on my classpath. I see you have it so good there.
In my ejb-jar.xml file, I set the meta-data flag to true so I did not get prompted on deployment to complete.
I set to "false" for one deployment to see what IBM generated for me. In the ejb-jar.xml it added the following (my MDB is named TaskMDB),
<assembly-descriptor>
<interceptor-binding>
<ejb-name>TaskMDB</ejb-name>
<interceptor-class>org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor</interceptor-class>
</interceptor-binding>
</assembly-descriptor>
<interceptors>
<interceptor>
<interceptor-class>org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor</interceptor-class>
<post-activate>
<lifecycle-callback-class>org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor</lifecycle-callback-class>
<lifecycle-callback-method>autowireBean</lifecycle-callback-method>
</post-activate>
<pre-passivate>
<lifecycle-callback-class>org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor</lifecycle-callback-class>
<lifecycle-callback-method>releaseBean</lifecycle-callback-method>
</pre-passivate>
<post-construct>
<lifecycle-callback-class>org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor</lifecycle-callback-class>
<lifecycle-callback-method>autowireBean</lifecycle-callback-method>
</post-construct>
<pre-destroy>
<lifecycle-callback-class>org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor</lifecycle-callback-class>
<lifecycle-callback-method>releaseBean</lifecycle-callback-method>
</pre-destroy>
</interceptor>
</interceptors>
Then I added what IBM generated (the assembly-descriptor and interceptors stanzas) back to my ejb-jar.xml and set the metadata-complete back to true.
Then it worked. Hope this helps.
Here is the full ejb-jar.xml
