Is it possible to define the screen definition in the
struts-config.xml? I think this will be more flexible.

Yes, that's a good idea, applicable for static screens.
We should still allow for programmatic definitions, though. Servlets or
servlet filters are good candidates for creating dynamic screen
definitions.

You can definitly do this in Struts as it stands (correct me if I'm wrong).
