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.
