    Description

      Here are few basic points on upgrading to JPA 2.0 API. This is an effort to consolidate the ongoing discussion on this issue and some how-to steps for those who are involved in developing JPA 2.0 features or writing tests.

      1. A draft version of JPA 2.0 Specification is published on Oct 31, 2008 [1]

      2. The source code of the new and modified JPA API is not available

      3. OpenJPA community has decided
      a) to develop its own version of JPA API Source code according to the spec [2].
      This decision helps us to control our own destiny especially in terms of few implemented classes.
      b) JPA API 2.0 Source will reside in Geronimo Source Code repository [2].
      Geronimo Developer Mr.David Jencks will commit the source on behalf of OpenJPA.
      c) JPA 2.0 related development work will be carried out on OpenJPA trunk [3]

      Few basic steps on the process

      1. Check out the JPA 2.0 API Source code from Geronimo SVN [4]

      2. Modify or add the new API or Annotation

      3. Create a patch and post the patch to Geronimo JIRA-4410 [5]

      4. After David has committed the patch, add a test case to OpenJPA that exercises the modified API
      even if the implementation of the API is incomplete. Simply annotate the test class
      with @AllowFailure. Please refer to [6] for further details.

      5. One iteration of the above steps were followed to add new Criteria API. The new API sources
      generated a snapshot version of JPA API jar. OpenJPA Maven build scripts are accordingly
      updated [7] to link against this new jar.
