JPA-App

Sample app created with JPA to practice JPSQL, JPA Criteria API and plain SQL queries in Java.

Goals

Main goals were to practice using plain SQL, JPQL and JPA Criteria API to write queries in Java. JPA was also used to persist data to MySQL DB.

How to use

In order to use this app, one must have access to a running MySQL instance.

Clone this repository, go to resources -> META_INF -> persistence-dev.xml

and change the variables according to your DB connection. Rename the file to persisntence.xml.

Just run the app. It works as a console app, and the commands are all written inside the main class.

*This is just a practice app and should not be considered as a fully working production-level app. It was really created in order to practice and as a simple reference.
