How to make a binding to the database in the registration form?

Question

MySQL

Hello! You need to make a java applet for the registration form (I know that applets are no longer in the topic, but still) and check the whole thing with Apache. As ide I use Netbeans with built-in Apache Tomcat.
I created a swing gui and embedded this unfinished applet into a blank web application. Everything is launched and displayed in the browser. Now I need to store the registration data in mysql database and do the email validation. Tell me what I need to use to work with the database and what is the best way to implement validation?

Answer 1
