Yes, it would be a plugin like Tiles and Validator. You provide an xml so it'll know what forms to create. When the plugin gets called by Struts at startup, it digests the xml and looks for the business objects you've listed. It creates FormBeanConfig objects (the internal Struts descriptor for a form-bean) based on them, then registers them in Struts.
