I should be a little more concise with property definition where as Employee would have an id that was a long. What you would like to see with Struts development is to have all properties of an ActionForm be Strings instead of integrating primitives. Again, thanks for all your work Jacob

No, you're doing the reverse of what I would not want to see:
public class EmployeeObject implements Employee, ActionForm
This is where you get into trouble over things like property types, as
well as making any user of EmployeeObject depend on Struts.
Your example correctly recognizes that EmployeeObject and EmployeeForm
are two totally differnt things, with different purposes and different
lifetimes. And, note that neither Employee nor EmployeeForm have any
dependencies on Struts APIs, so they are reasonable to use in non-web
environments as well.
