Stateless EJB, JEE6, SpringBeanAutowiringInterceptor

I've got a web application and we are using JEE 6. I've defined a Stateless EJB that I have also exposed as a web service with the following annotations.

Code:

---

@Stateless
@Interceptors(SpringBeanAutowiringInterceptor.class)
@WebService

---

The problem is that while the container recognizes the class as an EJB and a WebService, it seems that Spring is not being called and the rest of my classes initialization is never happening. I've defined a beanRefContext.xml file in the root of the classpath, which in turn loads the applicationContext.xml. But it seems that Spring is simply not being loaded. Am I overlooking something or isn't this possible with JEE 6 in a Web Container? Looking at the JEE docs it appears that Interceptors are supported, so I'm wondering why nothing is loading on the Spring side of things.

Thanks for the help..
