How to Use Spring from EJB3

This is a short instruction how to inject a spring-managed bean into EJB3 component.

1. Read SpringFratamework's reference here: http://static.springframework.org/spring/docs/2.5.x/reference/ejb.html#ejb-implementation-ejb3


2. Place to ejb module's classpath a file beanRefContext.xml:
   

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
   <beans>
   
    <bean id="myBeanFactory" class="org.springframework.context.support.ClassPathXmlApplicationContext">
     <constructor-arg value="myApplicationContext.xml"/>
    </bean>
   
   </beans>



3. Create application context file named myApplicationContext.xml and define You beans there. Place this file to the ejb module's classpath.


4. Annotate your Stateless Session Bean:
   

   @Stateless
   @Interceptors(org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor.class)
   public class MyFacadeBean implements MyFacade {
   
       @Autowired
       private MySpringComponent component;
       ...
       public void foo() {
           component.foo();//invocation 
       }
   }



5. Deploy and test Your application.
