JPA Using NetBeans and MySQL

In this article you will learn how to quickly get started with JPA. I will be using NetBeans and MySQL database to store data using JPA.

First let’s create a database:

create database JPA;

Create a new “Java Application” project in NetBeans. Right-click on the package, select new > other > persistence > Entity Class.

Give the new entity class a name and select the database connection. The IDE will generate the entity class with annotations.

Now create a JPA Controller. Right-click on the package > other > persistence > Jpa Controller Classes from Entity Classes.

Create an Application.java class where we create our entityManagerFactory:

EntityManagerFactory objFactory = Persistence.createEntityManagerFactory("JPAPU");
EntityManager manager = objFactory.createEntityManager();

Make sure the persistence-unit name from the persistence.xml file matches what you use in the code.

Now you are ready to run the project and see that it created a table NewEntity in JPA database.
