Subject [jira] Commented: (JDO-673) Interface JDOEntityManagerFactory does not compile with JPA 2.0
Date Fri, 28 Jan 2011 17:26:44 GMT

    [ https://issues.apache.org/jira/browse/JDO-673?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12988154#action_12988154
] 

Craig L Russell commented on JDO-673:
-------------------------------------

I propose that we remove the two interfaces JDOEntityManagerFactory and JDOEntityManager from
the 3.1 release. This is a backward compatibility issue but never worked with the published
JPA 2.0 specification. Since it is impossible to instantiate a class implementing this interface,
it probably is not an issue.

Any objections to removing these two interfaces?

> The JDO Interface JDOEntityManagerFactory extends both factory interfaces: PersistenceManagerFactory
(JDO) and EntityManagerFactory(JPA). Both interfaces define a method getProperties. In JDO
PersistenceManagerFactory the method returns Properties and in JPA EntityManagerFactory returns
Map<String, Object>.
> This retults in an error when compiling the api:
> JDOEntityManagerFactory.java:[28,7] types javax.jdo.PersistenceManagerFactory and javax.persistence.EntityManagerFactory
are incompatible; both define getProperties(), but with unrelated return types
> The the error did not occur earlier, because the api package used geronimo-jpa_3.0_spec
as the JPA dependeny, but his is the JPA 1.0 specification. The correct dependency is geronimo-jpa_2.0_spec.
> Possible solutions: change JDO PersistenceManagerFactory to return Map<String, Object>
or remove the JDOEntityManagerFactory and JDOEntityManger interfaces. Are these being used
by anyone?
