jsp/Javabean insert to database question

hey Kennethxu and rrz
its Gaz again
been playing a lot with registration form you helped me with earlier
and i am having trouble writting the data to the database
you c dreamweaver has server behaviours that insert data to a db however
if i do this it completely ignores the validation bean you helped with.
i looked at how to insert the data using a servlet
but am not sure how to incorporate the code into the java bean
the data is already retrieved with the set and get method
do i write another method to achieve a database insert?????
here is the old code:

package com.ora.jsp.beans.userinfo;

import java.io.*;
import java.util.*;
import com.ora.jsp.util.*;
