Key Tools

This section describes the support for EclipseLink provided by Oracle JDeveloper, Eclipse, and NetBeans development environments. Any tooling is compatible with EclipseLink, but these offer specific integration.

This section contains the following subsections:

Oracle JDeveloper

Oracle JDeveloper is a Java EE development environment with end-to-end support to develop, debug, and deploy e-business applications and web services.

For JDeveloper information and downloads, see:


JDeveloper includes a number of features to aid in the development of applications that use EclipseLink. These features include wizards to reverse engineer JPA entities from database tables and to generate EJB 3.0 Session Beans with EntityManager injection. It also includes methods for querying JPA entities and to test client generation.

JDeveloper tools enable you to quickly and easily configure and map your Java classes and JPA entities to different data sources, including relational databases and XML schemas without using code.

DBWSBuilder script (included in EclipseLink install) can be used to run the DBWSBuilder utility to generate the Web service. JDeveloper uses the API provided, but does not use the DBWSBuilder script directly.

For more information on Oracle JDeveloper's EclipseLink support, see JDeveloper online help.


The Eclipse IDE provides a number of features and utilities to help you create, run, and maintain applications that use JPA. These capabilities are extended if you install OEPE.

For Eclipse IDE information and downloads, see:


The Dali Java Persistence Tools Project provides extensible frameworks and tools for defining and editing object-relational mappings for JPA entities. JPA mapping support focuses on minimizing the complexity of mapping by providing entity generation wizards, design-time validation, and a robust UI for entity and persistence unit configuration.

For Dali information and downloads, see:


Other tools and utilities from the Oracle, open source, and third party vendor communities are available from the Eclipse Marketplace.



NetBeans IDE bundles Oracle GlassFish Server, which includes EclipseLink. The IDE provides full support for JPA-based code development. This support includes entity class wizards for constructing entities and editor hints to ensure that entities conform to the JPA specification. NetBeans also provides a persistence unit editor for constructing a persistence.xml file.
