 I'm wondering how folks handle field validation on jsp pages? I have a jsp
page and the
form variables need to be checked for proper values (numbers only, Date
format's and users not entering required info).

I have a bean managed entity bean and I was wondering how people
implement this type of validation logic. I'm sure it's not to be
implemented in the
.jsp page and should be checked in a session/entity bean? Another
question.......Is a session bean even necessary or should my entity bean
handle communications with the jsp pages?

Thanks for any help in advance.

J2EE newbie :-)
