3 Using EclipseLink with WebLogic Server

This chapter describes how to use EclipseLink as the persistence provider for applications deployed to Oracle WebLogic Server.

The chapter includes the following sections:

• Introduction to the Solution

• Implementing the Solution

• Additional Resources

Use Case

WebLogic Server developers, administrators, and user want to take advantage of all the persistence and transformation services provided by EclipseLink.

Solution

While WebLogic Server can use other persistence providers and EclipseLink can be used with other application servers, using WebLogic Server with EclipseLink provides a number of advantages.

Components

• WebLogic Server 12c or later. WebLogic Server includes EclipseLink.

  
  

  Note: EclipseLink's core functionality is provided by EclipseLink, the open source persistence framework from the Eclipse Foundation. EclipseLink implements Java Persistence API (JPA), Java Architecture for XML Binding (JAXB), and other standards-based persistence technologies, plus extensions to those standards. EclipseLink includes all of EclipseLink, plus additional functionality from Oracle.

  
  

• A compliant Java Database Connectivity (JDBC) database including Oracle Database, Oracle Express, MySQL, and so on.

• While it is not required, you may want to use a Java EE integrated development environment (IDE) for convenience during development.
