Wouldn't it be more useful to have the form object do the type conversion? 
Have a way to tell it the "JSP type" (99% String) and the "application type". 
Make the form objects smart enough to give you a properly typed result, much 
in the same way Hibernate's Session.load(Object obj, Object id) populates the 
right values into obj.

What you're basically asking for is user interface components, instead 
of simple input fields.  Fortunately, you can have that today with 
things like JavaServer Faces.  The user interface components there have 
the ability to automatically register the correct converter when you use 
a value binding expression to point the component at your model data - 
if it's an "int" property, the IntegerConverter will get used for you.
