The only reason that I think why people would think you mad for what, to me, 
seems a perfectly reasonable idea, is that people have been there, done that 
and it has been shown to be A Bad Idea(Tm). I'd be interested in comments 
before I attempt to go down this route.

I'm talking specifically about using entities in a web-app where I need to 
validate the length of  fields returned before trying to insert/update the 
database. I'd also like to make the column length available to the web 
framework (in this instance Struts 2) so I can set the size of the 
input/display elements to match their definition where appropriate.
