EclipseLink Extensions Incubator

This incubator will allow the development of extensions to EclipseLink that illustrate to users how similar extensions can be written.

This incubator is not intended to be a catch-all but to specifically deal with EclipseLink's public extension points allowing common extensions to be shared. Some of these extension points include:

  • Database Platforms
  • Expression Operators
  • Event Listeners
  • Query Re-directors
  • Server Platforms
  • Descriptor policies

Each extension will be maintained in its own project with self contained test cases to illustrate and verify its usage. EclipseLink users can then use these extensions as per their EPL/EDL licensing terms.

Promoting an Extension Project

Over time extensions in this incubator may be migrated into core functionality. The basic criteria for promoting include:

  1. Committers agree that the functionality is valuable to the user community and there is enough interest among the committers to support the functionality. This will require a vote of the current committers with at least 5 positive votes and no negative votes.
  2. The functionality in the extension project passes a design review of committers with any issues raised addressed
  3. There exists reasonable test cases, JavaDoc comments, and usage documentation to simplify its promotion

At that time the associated wiki content will be updated to include migration instructions to upgrade to the shipped implementation.

DatabasePlatform Promotion

Extension Usage Tracking

Each project in this incubator should have its own bug associated so that users of the extension can add themselves to the cc list and therefore be notified of enhancements and migration of functionality into the project's distributed bundles/JARs. The users copied on an extension incubator bug and votes cast for the bug will be used to help judge the community interest in a given project.

Support for Extensions

The support for these extension incubator projects is limited. It is recommended that issues encountered be raised in the bug.

Extension Projects

The following are the current extension projects maintained in this incubator.
