Thanks seems like the exact thing I wanted. But I'm stuck on struts 1.1 at
my workplace and based on this
http://www.niallp.pwp.blueyonder.co.uk/lazyactionform.html LazyActionform
has been added to struts 1.2.6
Is it possible to plug this thing into 1.1?has anybody done that?
Thanks
I haven't heard of anyone doing it, but you should be able to.
LazyDynaBean was added to Commons BeanUtils 1.7.0 and Struts 1.1
depends on a version prior to that. If you can upgrade to BeanUtils
1.7.0 then you have most of the functionality. You could use them as a
property in your ActionForm - or replicate the Struts
LazyValidatorForm (theres not too much to it), If you can't upgrade to
BeanUtils 1.7.0 then you could just grab the source code for the two
"lazy" classes you need (LazyDynaBean and LazyDynaClass) and they
should work OK with BeanUtils 1.6.1 - which is the version that Ships
with Struts 1.1
You can grab the source download from here for Commons BeanUtils:
