Issues using same domain classes in JPA and CXF/JAXB
I'm building an app that retrieves data with OpenJPA and tries to
serialize it in xml or json with CXF/JAXB. I'm using annotations on the
domain class to specify both the logical JPA (not physical) and JAXB
behavior (with the physical JPA in XML config). In theory I would think
this should work, but in my first test I found that CXF didn't serialize
the object that I retrieved from JPA.
After some thinking, I thought to write some debug code that prints out
the runtime annotations on the class, both for the class of the returned
instance, and the class that it's declared as. What I found (because I
realized I should have expected this) is that the runtime class didn't
have the required annotations that the declared class did. When JPA
enhanced the classes, it didn't copy the annotations.
My app currently doesn't use build-time enhancement or the javaagent. I
can't remember exactly what OpenJPA does in that situation. I think
it's still enhancing the class, but on demand.
Is this issue with non-copied annotations really an issue, or should I
look elsewhere for why CXF isn't serializing my data (I'm asking a
similar question on the CXF list)?

I posted a note on my build-time enhancement problem on Friday, and I
just posted a JIRA for this:

Ok, I'll work on a detailed description of my build-time enhancement
problems.
In short, I find that it's unable to find the fields of my class. It
throws "NoSuchFieldException" errors for the fields I specify in my
orm.xml, even though I have both the instance variable and public
getter/setter for the field.

Hi,
Just one other thing. Could you post your Category.java as well? I'm
thinking that the problem might be in the Category class...

Ok, so I'm running without enhancement at this point.

My attempt to set up load-time enhancement didn't work, due to struggles
with classloaders and other problems. I'm hoping I can somehow get
build-time enhancement working. Hopefully the JIRA I filed will make it
obvious either what I've done wrong, or what's wrong with the enhancer.

Re: Issues using same domain classes in JPA and CXF/JAXB
Posted by Craig L Russell <Cr...@Sun.COM>.
Hi Rick,
I don't know about three kinds of enhancement. Build time runs before
the classes are put into the jars for runtime. Runtime enhancement
enhances classes during loading. Running without enhancement is not
runtime enhancement.

I don't believe this is true. We disabled running *without
enhancement* but runtime (load time) enhancement should work just as
well as build time enhancement.

Re: Issues using same domain classes in JPA and CXF/JAXB
Posted by Rick Curtis <cu...@gmail.com>.
I'm going to suggest you spend a few more cycles on getting buildtime
enhancement working as runtime enhanced classes has a number of known
issues... Enough issues that we have disabled this support as the
default behavior in trunk. HTH
Thanks,
Rick

Well, presently I believe I'm just using "run-time" enhancement. I had
troubles with both "load-time" (javaagent) and "build-time" enhancement
(enhancer task). I'll eventually try to submit a ticket, particularly
for the problems I had with build-time enhancement.

Sorry I haven't followed this chain of emails, but what type of
enhancement are you using?

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.

Hi KARR, DAVID,
I'd say that not copying annotations over to enhanced classes is a
deficiency, if not a bug in OpenJPA.
OpenJPA is not the only consumer of runtime annotations.
Can you please file a JIRA for this issue?
Thanks,
Craig
