--------------------------------------------------------------
i am trying to use SpringBeanAutowiringInterceptor.class for DI in my Stateless EJB3 

@Stateless
@TransactionManagement(TransactionManagementType.CONTAINER)
@Interceptors({ExceptionHandler.clss, SpringBeanAutowiringInterceptor.class})
public class InstrumentServiceEJB implements instrumentServiceRemote{

@Autowired
private InstrumentService instrService;

......
}

here is my beanRefContext.xml:
<? xml version=++"1.0" encoding="UTF-8"?>++
++<beans xmlns="....">++
++<bean class="org.springframework.context.support.ClassPathXmlApplicationContext">++
++<constructor-arg>++
++<list>++
++<value>/META-INF/applicationContext.xml</value>++
++</list>++
++</constructor-arg>++
++</beans>++

+applicationContext.xml:+

<? xml version=++"1.0" encoding="UTF-8"?>++
++<beans xmlns="....">++

<context:annotation-config/>

 <bean id=++"instrService" class="com.company.business.InstrumentServiceCore"/>++
+</beans>+
+
+

here is my Remote interface
@Remote
public interface InstrumentService{
......
}

and i have two implementation of above InstrumentService , one is InstrumentServiceEJB and another one is InstrumentServiceCore.

i have put beanRefContext and applicationContext.xml under META-INF/folder

now when i tried to call my EJB, (I am invoking my EJB through a web service call ) it throws Exception like :

javax.ejb.EJBException: java.lang.RuntimeException: org.springframework.beans.factory.access.BootstrapException: Unable to return specified BeanFactory instance: factory key [null], from group with resource name [classpath*:beanRefContext.xml]; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [org.springframework.beans.factory.BeanFactory] is defined: expected single bean but found 0
