Autowiring in EJB3 SLSB on JBoss5

[Iassan]

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:

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:

<?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"

</ejb-jar>

beanRefContext.xml:

				<value>applicationContext.xml</value>
			</list>
		</constructor-arg>
	</bean>
</beans>

applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	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:

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):

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.

The same here but Jboss 5.1.0 and auto-wiring simple pojos.

Mainly it seems to happen when an persisted ejbTimer method (@Timeout) is invoked of the SLSB and it is fired directly after deployment

Seems like a classloading issue to me - not finding the classpath*:beanRefContext.xml. Without the @Timeout annotation it seems to work.

Any pointers?
