RE: Hi Ted, any more on ?
Did you take a look at
Middlegen(http://sourceforge.net/projects/middlegen/)?
It's pretty close to what you are describing. In fact it goes couple steps
backwards and forwards generating JSPs/Struts action classes directly from
database. It has plug-ins for EJB and JDO. If have a site with simple forms,
it saves you a lot of time by generating all the forms with get/set.

Hi Ted,
Has the <html:control> you mention below been implemented already
or is it in the works at all?
Thanks,
