I will join in too on this one... What it sounds like you've done is put business logic in your actions, when actions should simple call interactions between business delegates or business facades. (See Sun's J2EE Patterns).
By mingling business logic in your actions, you've forever committed your development within the Struts framework-- hence your probable need to now expose your work via web services. The action code should be only a few lines if done correctly, simply acting as an adapter to some business provider. That would leave the code in your action to simply pull data from ActionForms, or validate flows. If you want to do Web Services, have the services talk to your business providers, the same ones your actions would talk to.

Business logic should be just that, business logic. Shouldn't a web service just provide another view of your business logic. And as another view shouldn't it be relying on your controller to provide the manipulation of the logic to get to its view? isn't this exactly the right place to put this kind of thing? >Or do you see here a solution for all those folks who've not followed best >practice and have intermingled Controller functionality with Business >logic..? > Aren't you just intermingling the view with the model if you expose your logic?
