Is there a Spring HandlerAdapter implementation for Struts?

This is just a curiosity question. I know that Spring can be used in a Struts ActionServlet (sp?) via certain means, but I was wondering if there was a HandlerAdapter that allowed old Struts code to be ported immediately to a Spring Dispa开发者_如何学PythontcherServlet to use the DispatcherServlet as the front controller.

All of the Spring-Struts interface code is in the org.springframework.web.struts package, and there's no HandlerAdapter implementation in there, just the delegation stuff like DelegatingRequestProcessor.

I suppose the Struts framework is just too awful even for Spring's integration abilities.
