I think it is quite reasonable to optionally generate JavaScript for client side
validations of the things that make sense to validate there (in addition to the
server side validation code being automatically generated/processed as well,
because you can never trust a client to actually do the tests for you :-).  I'll
add your name to the list of volunteers for this, and you might want to join
STRUTS-DEV (if you have not already) to participate in the upcoming discussions
on implementing this feature.
