Quick and dirty howto : Use Hibernate in Glassfish V2

UPDATE:

As Leon pointed in comments, it’s not a good idea to put the hibernate jars in the app server classpath like in this post. Hibernate community had published a howto explaining how to use Hibernate in Glassfish but the link has expired. Here is a copy from google cache:

To use hibernate with glassfish, all you have to do is put hibernate and its dependencies into your EAR file. This might also with with a WAR file.

In your persistence.xml, specify hibernate using this tag:

<provider>org.hibernate.ejb.HibernatePersistence</provider>

You can also specify hibernate properties as usual, for example:

<properties>  <property name=”hibernate.hbm2ddl.auto” value=”none”/></properties></blockquote>

For my first post here I’ll write a quick and dirty howto for using Hibernate inside the Glassfish V2 container.

1. Download Hibernate projects
2. Put’em in the domain’s lib dir
3. Change your persistence.xml file
4. Enjoy :)

Details are following :

1) Download Hibernate projects

Get your favorite browser to the Hibernate download page and get the following files :

• Hibernate Core 3.2.5.ga
• Hibernate Annotations 3.3.0 GA
• Hibernate EntityManager 3.3.1 GA
• Hibernate Validator 3.0.0 GA
• Hibernate Search 3.0.0 GA

Theses versions were the last stable releases versions when this blog was written, addapt them to your own era.

Unpack them all.

2) Put the right jars in the domain’s lib dir

Take the following JARs :

• hibernate3.jar
• hibernate-annotations.jar
• hibernate-commons-annotations.jar
• hibernate-entitymanager.jar
• hibernate-search.jar
• hibernate-validator.jar
• antlr-2.7.6.jar
• asm-attrs.jar
• asm.jar
• c3p0-0.9.1.jar
• cglib-2.1.3.jar
• commons-collections-2.1.1.jar
• commons-logging-1.0.4.jar
• concurrent-1.3.2.jar
• dom4j-1.6.1.jar
• ehcache-1.2.3.jar
• javassist.jar
• jboss-archive-browsing.jar
• log4j-1.2.11.jar
• lucene-core-2.2.0.jar

… and put them all in the “lib/” subdirectory of your Glassfish domain.

3) Change your persistence.xml file

Change your persistence.xml file to build a persistence unit that use Hibernate persistence mechanism :

Here is an example :

1. <?xml version=“1.0″ encoding=“UTF-8″?>

2. <persistence version=“1.0″ xmlns=“http://java.sun.com/xml/ns/persistence&#8221;

3. xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance&#8221;

4. xsi:schemaLocation=“http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd&#8221;>

5. <persistence-unit name=“MyEntitiesPU” transaction-type=“JTA”>

6. <provider>org.hibernate.ejb.HibernatePersistence</provider>

7. <jta-data-source>jdbc/__default</jta-data-source>

8. <class>my.app.model.entities.Device</class>

9. <exclude-unlisted-classes>true</exclude-unlisted-classes>

10. <properties>

11. <property name=“hibernate.dialect” value=“org.hibernate.dialect.DerbyDialect”/>

12. <property name=“hibernate.hbm2ddl.auto” value=“create-drop”/>

13. </properties>

14. </persistence-unit>

15. </persistence>

4) Enjoy :)

Restart your glassfish and enjoy Hibernate !
