thanks. i won't go that route. i noticed your example (in the first response) and i realized that i may trying to push some business logic into the Action class. and, i don't think that's too good of a practice. i simply revised my Service class to hold these values (booleans, String, int, etc...) and now the problem goes away. it's a workaround.
if anyone is reading this post and knows how to use struts2 (w/ convention plugin) + spring to construct Action classes, please let me know. the examples i've seen are only with struts1 (and though not too complicated, seem verbose with the xml).
