In section 8.5 of the spec, it states: An observer method must be a method of a simple bean implementation class or session bean implementation class. An observer method may be either static or non-static. If the bean is a session bean, the observer method must be a business method of the EJB or a static method of the bean class. In the case of the latter, what is the behavior of the container if a session bean violates that statement? Perhaps DefinitionException? Usually the spec is explicit about the exception thrown.
