This guide gets you started building enterprise Java beans for Oracle Containers for J2EE (OC4J) using:

It includes code examples to help you develop your application.

The Orion persistence manager is deprecated. Oracle recommends that you use OC4J and the TopLink JPA persistence provider for new development. Using the migration tool (see "Migrating to the TopLink EJB 2.1 Persistence Manager"), you can easily migrate an existing OC4J application that uses EJB 2.0 entity beans with the Orion persistence manager to use EJB 2.0 entity beans with the TopLink persistence manager.

If you have questions about OC4J, see the OC4J user's forum at

If you have questions or feedback about this documentation, see the documentation feedback forum at


Anyone developing Enterprise JavaBeans for OC4J will benefit from reading this guide. Written especially for programmers, it will also be of value to architects, systems analysts, project managers, and others interested in EJB applications deployed to OC4J.

This guide assumes that you already have a working knowledge of Java EE and the EJB 3.0 and EJB 2.1 specifications.

Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
