Chapter 7. Hibernate Tools basics in CodeReady Studio
Hibernate Tools is a collection of tools for projects related to Hibernate version 5 and earlier. The tools provide Eclipse plugins for reverse engineering, code generation, visualization, and interaction with Hibernate.
7.1. Creating a new JPA project
The following section describes how to create a new JPA project in CodeReady Studio.
Prerequisites
You need to start the Sakila database server before you can create a new JPA project in CodeReady Studio.
- Download the h2 version of the Sakila database.
-
Navigate to the directory that contains the
runh2.shfile. Execute the
runh2.shfile:./runh2.sh
$ ./runh2.shCopy to Clipboard Copied! Toggle word wrap Toggle overflow
Procedure

- Click the down-arrow in the Driver class field to select the driver.
- Click the down-arrow in the Connection URL field to select the URL.
- Click .
7.6. Creating a Hibernate console configuration file
A console configuration file describes how the Hibernate plugin configures Hibernate. It also describes the configuration files and classpaths needed to load the POJOs, JDBC drivers, and so on. It is required to make use of query prototyping, reverse engineering and code generation. You can have multiple console configurations per project, however, one configuration is sufficient.
The following section describes how to create a Hibernate console configuration file in CodeReady Studio.
Procedure
- Start CodeReady Studio.
Press Ctrl+N.
The Select a wizard window appears.
