Phonebook using jsf, mysql, tomcat?

Question

MySQL

I was given a task in practice - to make a simple directory using the Eclipse IDE, JavaServer Facelets, Tomcat server (8.5 version), and Mysql database, so that the first name, last name and phone number are saved in the database at the click of a button in the jsf interface. Jsf form is already there; tomcat installed, working; pb database on MySQL, which has 4 fields: person_id, fname, lname, pnum, set; a class with a Managed Bean, in which the id of a person is his first name, last name, phone number (setter and getter for each field of the database, does Managed Bean seem to be for logic?). Actually, I need the data to be saved in the database, and on the jsf form it would be possible to display, add, delete and change the data.
