JSP Form Validation

[dreampolice]

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.

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 I would not use a bean and have a getter and setter method for all 20 fields?

I dont have Struts and need to know the best way to do this.
Can anyone give me an example or ideas on this?

I think you should do the validation client-side with Javascript.

Thanks, some people turn off JavaScript in my environment which is why I want to do server side validation.

Please advise.

Look at Spring (and for this especially Spring MVC) (

http://www.springframework.org

). Makes validation a breeze (and integrates nicely with ORM tools like Hibernate and iBatis as well to make database access from your controllers smooth).

i don't know if this works.

after the validation,use request.getParameter (...) to get each value (meaning 20 of them), then insert the values into SQL into database.
