  • Autowiring in EJB3 SLSB on JBoss5

    Hi everyone,

    I have a problem with autowiring Spring beans into EJB3. I've read most articles about it (including, of course, Spring documentation), so I know to use SpringBeanAutowiringInterceptor. I believe I have proper configuration as people were saying was OK, for example here: http://forum.springsource.org/showthread.php?t=49267. But everyone uses JBoss 4.2, I'm using 5.0.1.GA, and I think that it makes some difference.

    Here's my configuration and code:
    EJB:
    Code:
    package foo.ejb;
    
    import javax.ejb.Stateless;
    import org.apache.log4j.Logger;
    import org.springframework.beans.factory.annotation.Autowired;
    import foo.dao.SthDAO;
    import foo.vo.SthVO;
    
    @Stateless(name = "foo/SessionService", mappedName = "foo/SessionService")
    public class SessionServiceEJB implements SessionService {
    
    	private static final Logger logger = Logger.getLogger(SessionServiceEJB.class);
    
    	@Autowired
    	private SthDAO sthDAO;
    
    	@Override
    	public SthVO getSthById(Long id) {
    		logger.debug("getSthById(" + id + "), sthDAO: " + sthDAO);
    		return sthDAO.getSthById(id);
    	}
    }
    ejb-jar.xml:
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    
    <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" version="3.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd">

    			<interceptor-class>org.springframework.ejb.interceptor.SpringBeanAutowiringInterceptor</interceptor-class>
    		</interceptor-binding>
    	</assembly-descriptor>
    </ejb-jar>
    beanRefContext.xml:
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    				<value>applicationContext.xml</value>
    			</list>
    		</constructor-arg>
    	</bean>
    </beans>
    applicationContext.xml:
    Code:
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"

    	default-autowire="byType">
    	<context:component-scan base-package="foo" />
    	<jee:jndi-lookup id="fooEntityManagerFactory" jndi-name="persistence-units/foo"/>
    </beans>
    I see, that Spring is being used, because in logs I can see:
    Code:
    INFO  [NamedXmlApplicationContext] Bean factory for application context [org.jboss.spring.factory.NamedXmlApplicationContext@1e0a078]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1c56526
    But any try to use EJB3 from Tomcat ends with (Tomcat side):
    Code:
    Caused by: 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
    Has anyone managed to autowire anything into EJB3 on JBoss5? I need that in EAR archive.

    Regards
