Richard Zowalla resolved OPENJPA-1428.
--------------------------------------
Resolution: Won't Fix
Closing as obsolete during backlog cleanup: RuntimeUnenhancedClasses defaults
to "unsupported" (OpenJPAConfigurationImpl.java:641), so entities are the
enhanced original class with its annotations, not a generated subclass. Please
reopen if this still happens with OpenJPA 4.x.
> Enhanced versions of classes lose annotations in original classes

> Key: OPENJPA-1428
> URL: https://issues.apache.org/jira/browse/OPENJPA-1428
> Project: OpenJPA
> Issue Type: Bug
> Components: jpa
> Affects Versions: 1.2.1
> Reporter: David M. Karr
> Priority: Minor
>
> I am attempting to construct an application using OpenJPA and CXF such that
> the domain classes that OpenJPA maps the database to are the same beans that
> CXF is using to serialize XML/JSON results through JAXB/Jackson. I'm using
> the logical JPA annotations along with physical settings in the orm.xml. I'm
> also using JAXB annotations to specify how the class will be serialized.
> In order for that serialization to work, the objects being created by OpenJPA
> have to have the JAXB annotations that I've put on the class. If I just
> manually create an instance of that class and serialize it, it works fine.
> However, I've discovered that if I use the object instance that I got from
> JPA, it doesn't serialize. CXF complains that it can't find a "message body
> writer" for the class of the instance. When I looked deeper, I discovered
> that the class annotations that I put on the class to control its
> serialization are not present on the class of the instance I got back from
> OpenJPA.
> I implemented a straightforward workaround that simply creates an instance of
> my class and uses "BeanUtils.copyProperties()" to copy from the
> OpenJPA-created instance to my manually created instance. I then serialize
> that. It works fine. I'd prefer not to have this workaround, as I was trying
> to avoid the step of copying the properties of the OpenJPA instance to a
> serializable instance.
