Chapter 4 Generating Hibernate Persistent Objects and JSF Pages

Defining the Hibernate database configuration parameters

Hibernate can support multiple databases. You need to define database configuration parameters. The database configuration parameters are stored in the configuration file, hibernate.cfg.xml .

Steps To define Hibernate configuration parameters:

  1. Open the model property sheet and click the Hibernate Configuration tab:
  2. Define the type of database, JDBC driver, connection URL, JDBC driver jar file path, user name, password, etc.

Option Description
Dialect Specifies the dialect, and hence the type of database.

Hibert Tag: dialect
JDBC driver class Specifies the JDBC driver class.

Hibert Tag: connection.driver_class
Connection URL Specifies the JDBC connection URL string.

Hibert Tag: connection.url
JDBC driver jar Specifies the JDBC driver jar file path.

Hibert Tag: N/A
User name Specifies the database user name.

Hibert Tag: connection.username
Password Specifies the database user password.

Hibert Tag: connection.password

Hibert Tag: hbm2ddl.auto
Package prefix Specifies a namespace prefix for all the packages in the model.

You can verify the configuration parameters in the Preview tab.
