I use it for my login actions when I'm not using container managed security.
My typical worse case action is:
TheForm theForm = (TheForm) form;
ActionErrors errors = form.validate();
if( errors.isEmpty()) {
errors = weirdValidations( form);
if( errors.isEmpty()) {
TheVo vo = new TheVo();
BeanUtils.copyProperties( vo, theForm);
getTheBusinessObject.doSomething( vo);
} else {
forward = forwardToError( errors);
}
} else {
forward = forwardToError( errors);
}
Now, I don't know about you, but this is much nicer, cleaner and easier to debug and
maintain then having a whole bunch of validation code and copy code in the action.
