EclipseLink/Examples/JPA/GlassFishV3 Web Tutorial

EclipseLink JPA Deployed on GlassFish 3 using Eclipse WTP

Please refer to the GlassFish V2 page for generic EclipseLink on GlassFish Issues.

If you want to get a small web application running quickly on GlassFish - the services provided by the Web Tools Project plugin in the Eclipse IDE can take care of the deployment details and set the server into debug mode for you.

This basic example details how to use Eclipse to run/debug a minimum J2EE web application servlet using EclipseLink JPA as the persistence provider. The goal of this example is to detail the minimum steps needed to run EclipseLink inside GlassFish using the Eclipse IDE - at this point no presentation/controller layer such as JSF, Spring or Struts will be used beyond a basic HttpServlet so we can concentrate on the the integration layer JPA setup.

The DALI project was used to generate Entities from a schema with sequences already populated.

Development Environment

Software: Eclipse IDE for Java EE 3.4 Ganymede (June 2008 +) with all 5 packages (DTP 1.6, EMF 2.4, GEF 3.4, WTP 3.0, XSD 2.4), Oracle 11g DB 11.1.0.6.0, Java JDK 1.6.0_04, GlassFish V3 Prelude

This example will run fine with any Database that EclipseLink supports.

Prerequisites

Install Eclipse EE

  • I installed a clean version of Eclipse Ganymede (June 2008) with all of WTP 3.0

Install a Database

  • In this example I am using Oracle 11g, the table schemas have already been created manually and all entity java classes have been generated using the Eclipse DALI tool.

  • It is recommended that you install the GlassFish V3 Prelude version and use the latest 1.0.9+ V3 SNAPSHOT Eclipse 3.4 Server plugin to run/debug the prelude server.
  • Using the GlassFish V3 Prelude install - we select the SNAPSHOT version of the plugin after using "Download Additional Server Adapters" to get a 1.0.9 GlassFish plugin or later.

All of deployment, JNDI setup, persistence.xml configuration, jpql query example - in progress when we start JEE6 examples as V3 Prelude (a JEE6) server does not support deploying JEE5 EAR projects......
