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. > > Thanks, > Rick > > On Dec 13, 2009, at 3:53 PM, "KARR, DAVID (ATTCINW)" <[email protected]> > wrote: > > >> -----Original Message----- > >> From: Rick Curtis [mailto:[email protected]] > >> Sent: Sunday, December 13, 2009 10:50 AM > >> To: [email protected] > >> Subject: Re: Issues using same domain classes in JPA and CXF/JAXB > >> > >> Sorry I haven't followed this chain of emails, but what type of > >> enhancement are you using? > > > > Well, presently I believe I'm just using "run-time" enhancement.
