Java Persistence API

Improve performance. Java EE 5 fuels efficiency.   » Download Java EE SDK Overview Technologies Reference Community Support Dev Kit Downloads   At a Glance Java EE 5 Web Services Web Application Enterprise Application Management Java Persistence API The Java Persistence API provides a POJO persistence model for object-relational mapping. The Java Persistence API was developed by the EJB 3.0 software expert group as part of JSR 220, but its use is not limited to EJB software components. It can also be used directly by web applications and application clients, and even outside the Java EE platform, for example, in Java SE applications. See JSR 220. Downloads   Implementation of Java Persistence API Downloads To download a fully tested and compatible build, chose the GlassFish v1 FCS branch and download the v1 ur1 b14 binary bundle.   Articles   Using Java Persistence API Within a Visual Web Application NetBeans IDE 6.0, the Visual Web tools, and Java Persistence API (JPA) give you greater flexibility for writing database-dependent applications.   Using the Java Persistence API on the Desktop Learn how the Java Persistence API allows you to use POJOs in desktop applications.   The Java Persistence API: A Simpler Programming Model for Entity Persistence See how much easier and streamlined it is to code for entity persistence with EJB 3.0 and the Java Persistence API than with the EJB 2.1 programming model.   Tech Tips   Combining JavaServer Faces Technology, Spring, and the Java Persistence API How to Get the Best Performance Out of a Java Persistence Implementation Using Generics With Java Persistence Pitfalls in Constructing Java Persistence Query Language Queries Using Java Persistence With JavaServer Faces Technology The Java Persistence Query Language Using Multiple Databases in a Java Persistence Application Inheritance and the Java Persistence API Converting a POJO to a Persistent Entity   Resources   Java Persistence Example This is a simple example that uses only two entities—a Customer and an Order, with OneToMany relationships between them. Java Persistence API FAQ This FAQ introduces the Java Persistence API and discusses the Java Persistence API's advantages and how it is being developed.   Tutorials   Introduction to the Java Persistence API Persistence in the Web Tier Persistence in the EJB Tier The Java Persistence Query Language   Related Blogs   Sample Application Using JAX-WS, JavaServer Faces, Spring, and Java Persistence APIs on Glassfish Sample Application Using JAX-WS, JavaServer Faces, Enterprise JavaBeans 3.0, and Java Persistence APIs on Glassfish Sample Application Using JavaServer Faces Technology, Seam, and Java Persistence APIs on GlassFish Using JavaServer Faces, Spring 2.0, and Java Persistence APIs in an Application Java Persistence Query Return Types Improving Support for Generics in the Java Persistence API Native Query in Java Persistence Query Language Using Relationships in the Java Persistence Query Language Named Query in Java Persistence Query Language More Good Examples in Java Persistence Query Language Enumerated Annotation in GlassFish Persistence How to Use LIKE Expression in Java Persistence Query Language Elvis, Meet NetBeans Using Java Persistence API in Java EE Platform - Part II   » See more Community   GlassFish Community Participate in the community development of the latest version of Sun Java System Application Server, which implements the newest features in the Java EE 5 platform.
