3.3. JMX Integration

JMX is the J2EE standard for the management of Java components. Hibernate can be managed via a JMX standard service. An MBean implementation is provided in the distribution: org.hibernate.jmx.HibernateService.
For an example of how to deploy Hibernate as a JMX service on the JBoss Enterprise Application Platform, please see the JBoss User Guide. JBoss Enterprise Application Platform also provides these benefits if you deploy using JMX:
  • Session Management: the Hibernate Session's life cycle can be automatically bound to the scope of a JTA transaction. This means that you no longer have to manually open and close the Session; this becomes the job of a JBoss EJB interceptor. You also do not have to worry about transaction demarcation in your code (if you would like to write a portable persistence layer use the optional Hibernate Transaction API for this). You call the HibernateContext to access a Session.
  • HAR deployment: the Hibernate JMX service is deployed using a JBoss service deployment descriptor in an EAR and/or SAR file, as it supports all the usual configuration options of a Hibernate SessionFactory. However, you still need to name all your mapping files in the deployment descriptor. If you use the optional HAR deployment, JBoss will automatically detect all mapping files in your HAR file.
Consult the JBoss Enterprise Application Platform user guide for more information about these options.
