No. It's not possible to do what you're thinking. The web is a
distributed environment and allowing this sort of client-server
technique would cause big speed/congestion problems.
You have two options for validation:
1. download JavaScript validation code with the page
Have JS check the field before the form is submitted... allow the
submit if it's okay but don't if it's not.
2. have the servlet do all your validation for you.
