Using JPA 2.0 with WebLogic Server 10.3.4 and Eclipse
By Greg Stachnick-Oracle on Feb 09, 2011
Beginning in Oracle Enterprise Pack for Eclipse (OEPE) 18.104.22.168.1, we introduced a new feature for WebLogic Server configuration called Server Extensions. Similar in concept to project facets, Server Extensions allow us to install additional technologies, libraries, configurations, etc into an existing server runtime.
WebLogic Server 10.3.4 introduces new support for Java Persistence 2.0, the new JEE 6 standard entity access. In order to start developing JPA 2.0 applications with WebLogic Server 10.3.4, a SmartUpdate patch must be applied to add and configure the EclipseLink libraries. More information on the manual EclipseLink installation and configuration can be found here.
OEPE provides a Server Extension for JPA 2.0, making the addition and configuration of JPA 2.0 and EclipseLink much easier. When defining a new WebLogic Server 10.3.4 configuration, simply click the Install link for Java Persistence 2.0 and OEPE will take care of the WebLogic Server enablement for JPA 2.0.
