The one thing I don't understand about this is why it is configured through the 
ActionMapping's parameter?

The method names in the Action can't be configured so the only value I could 
see is if the Action is reused and you wanted to "obfuscate" in a different way 
for different mappings. But I don't really see much need for that.

How about adding the parameter list to the constructor, so you would do 
something like...

    private ActionDispatcher dispatcher
                    = new ParameterListActionDispatcher(this,
                      "save,back,recalc=recalculate,default=save");

or maybe add methods...

  public class FooAction extends Action {

    private ParameterListActionDispatcher dispatcher
                    = new ParameterListActionDispatcher(this);

    public FooAction() {
        dispatcher.addMethodParam("save");
        dispatcher.addMethodParam("back");
        dispatcher.addMethodParam("recalc", "recalculate");
        dispatcher.addDefaultParam("save");
    }

  }

...or perhaps both.
