Dianne Richards commented on OPENJPA-773:
-----------------------------------------

The JPA 2.0 spec adds the following method to the EntityManagerFactoryInterface: Map<String,Object> getProperties(). The current openjpa OpenJPAEntityManagerFactory interface has the following method, which is incompatible: Properties getProperties(). I'me changing the current OpenJPAEntityManagerFactory interface in trunk under OPENJPA-849 to return a Map. This need to be documented to users since it will break apps that use this method.

> 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.
