Hibernate with JPA

To use Hibernate as a persistence provider for the Java Persistence API (JPA) you must include the following jar files into your classpath:

• From Hibernate Entity Manager
  • hibernate-entitymanager.jar
  • lib/hibernate-annotations.jar
  • lib/hibernate-commons-annotations.jar
  • lib/jboss-archive-browsing.jar
• From Hibernate Core
  • hibernate3.jar
  • lib/antlr-2.7.6.jar
  • lib/asm-attrs.jar
  • lib/asm.jar
  • lib/c3p0-0.9.1.jar
  • lib/cglib-2.1.3.jar
  • lib/commons-collections-2.1.1.jar
  • lib/commons-logging-1.0.4.jar
  • lib/concurrent-1.3.2.jar
  • lib/dom4j-1.6.1.jar
  • lib/ehcache-1.2.3.jar
  • lib/javassist.jar
  • lib/log4j-1.2.11.jar

If you use a Java SE project you must also include the javaee.jar file from the Java EE 5 SDK.

Here is a sample persistence.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
  xmlns="http://java.sun.com/xml/ns/persistence"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
  http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

  <persistence-unit name="webstore-ejbPU" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>jdbc/webstore</jta-data-source>
    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
      <property name="hibernate.hbm2ddl.auto" value="update"/>
    </properties>
  </persistence-unit>
</persistence>
