Given a struts application including various JSP, form beans, and actions. Is it feasible to convert it into a "struts + Spring + hibernate" application ? what in my mind is --- I use spring light weight frame as a general middle layer framework, keep the JSP stuff untouched, make those actions extend "Action" and modify those .xml descriptor files, if we don't use any Hibernate I guess that's the only change we need, do I miss anything ?
If I want to add Hibernate then I need create those Hbernate related xml, call hibernate API from the Action classes, basically that's it. Right ?
