http://community.jboss.org/message/631426#631426 -------------------------------------------------------------- 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
