Subject [jira] [Commented] (JDO-607) Require no-args constructor for PMF implementations and add static methods to PMF interface
Date Fri, 13 Jan 2012 18:20:39 GMT

    [ https://issues.apache.org/jira/browse/JDO-607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13185730#comment-13185730
] 

Craig L Russell commented on JDO-607:
-------------------------------------

The suggested approach is fundamentally broken.

A new approach is needed, specifically to define a new interface, PersistenceManagerFactoryService
with two methods: 

createPersistenceManagerFactory(Map) 
createPersistenceManagerFactory(Map, Map)

The interface would be implemented by the JDO implementation and a reference to the service
would go into the implementation jar.

> In order to use Java 6 ServiceLoader to instantiate PMF, the class needs to implement
a no-args constructor, and the PMF interface needs to define the methods that are currently
static (and therefore not defined in the interface).
