It looks to me like the container is having a problem retrieving your session bean. When you @In(ject) a session bean Seam will retrieve it from JNDI. What you are doing in your factory method is simply instantiating the class, which will not have the Seam or EJB interceptors applied to it. Why don't you remove the factory and post the stack trace.
