    Dependecy Injection through Spring in EJB 3.0

    Amit Ajmani Newbie

      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

          Just want to correct the type above:

           

          My interface hierarchy are

           

          public interface InstrumentService{

          ...

          }

           

          @Remote

          public interface InstrumentServiceRemote extends InstrumentService{

          ....

          }

           

          //annotated with stateless and transaction and SpringBeanAutoWiring (as above)

          public class InstrumentServiceEJB implements InstrumentServiceRemote{

           

          @Autowired

          private InstrumentService instrService;

           

          .....

          }

           

          public class InstrumentServiceCore implements InstrumentService{

          .....

          }

           

          the instrService in EJB need to be initialized with InstrumentServiceCore .....
