Done: <https://issues.apache.org/jira/browse/OPENJPA-1428>. In the meantime, I have a workaround using a generic method that basically creates an instance of my class, then uses "BeanUtils.copyProperties()" to copy over everything. That object then serializes fine, because its class has the annotations. > On Dec 12, 2009, at 2:19 PM, KARR, DAVID (ATTCINW) wrote: > > > I'm building an app that retrieves data with OpenJPA and tries to > > serialize it in xml or json with CXF/JAXB.
