I want to create a JSP Form page (first.jsp) on Tomcat 4.1.27 with a
form that has about 20 input entries where the form will validate all
20 fields and show validation errors on the same page as the original
form page (first.jsp). For example, if someone has a blank entry on
the Firstname field then it will show this message in red next to the
field: First Name is required.

If the data passes the validations it will populate an Oracle
database. Please advise any suggestions on how I should do this. I was
thinking of submitting the fields to a Controller servlet then use the
Enumeration class to get all field values where I would check for
blanks and valid email address. I assume if I use a bean and have a
getter and setter method for each field I would then have 40 methods
(20 setter and 20 getter methods) in the bean class.

I dont have Struts and need to know the best way to do this. Can
anyone give me ideas or examples of how do to this?
