However, I extended the base struts 2 action with a layer-aware interface to get the reference to a layer and an interceptor to inject the reference. All my actions extend the new base class and I can retrieve the business layer with a simple getLayer() method. This means I don't need to fiddle around with the session object in my actions.

Hi, Maybe sticking with the core j2ee patterns would be better. As explained in the ServiceLocator pattern http://java.sun.com/blueprints/patterns/ServiceLocator.html you maigh associate a singleton to your servicelocator while maintaining a cache to the already lookup()ed facades.
