This is the EclipseLink FAQ, please feel free to post "common" questions here about EclipseLink that you believe "other" users we find "useful". Please do not use this to ask general questions or for issues you are having using the product or for support, please post these types of questions to the EclipseLink Forum.

Please add your questions to the most suitable category or create a new category. (to add a question edit this page and provide a link to your question).

General

These are general frequently asked questions focused on what the Eclipse Persistence Services (EclipseLink) project is, what the various persistence services are as well as general questions about the project.

Complete list of general questions and their answers

EclipseLink's Caching

EclipseLink's object-caching is one of its most powerful and unique features. The caching applies to users of EclipseLink's JPA (and Native ORM), DBWS, and EIS. These frequently asked questions focus on how EclipseLink's entity cache works and how it is most commonly used and configured.

See "Understanding Caching" in the Understanding EclipseLink (concepts guide) and "Enhancing Performance" in the EclipseLink Solutions Guide, both available in the EclipseLink Documentation Center, for additional information.

EclipseLink JPA, ORM

See the EclipseLink JPA Extensions Guide in the EclipseLink Documentation Center for more information.
