Chapter 6. Hibernate on JBoss Web Server
Hibernate is an object-relational mapping framework. It is packaged independently from JBoss Web Server. This packaged version is used on all supported platforms.
Hibernate is used in the same way it is used for a regular Tomcat installation: the Hibernate JAR files are added into a deployment WAR file. Tomcat provides a default connection pooling mechanism, which is defined in context.xml. However, persistence.xml and web.xml are also required. The example below shows a configuration with the Tomcat connection pooling mechanism.
