Re: [eclipselink-users] Help! Weird EclipseLink exception
|
Hi Zhou,
Looks like classloading issue - please make sure that eclipselink.jar is not
included on the classpath more than once.
If that's not the case, may be you could verify whether the test works with
Spring 2.5?
Also it seem that you meant to use @OrderBy, not @OrderColumn annotation
(@OrderColumn(name="mail_id desc") is illegal, but @OrderBy(name="mail_id
desc") is ok). Does it work with OrderBy?
If not, try removing both OrderBy and OrderColumn - does it work now? If
not, what the exception you are getting?
Thanks,
Andrei

Subject: [eclipselink-users] Help! Weird EclipseLink exception
Hi all,
I'm new for using EclipseLink as JPA implementation as I'd like to use JPA
2.0 with latest Spring 3.
I've encountered a weird exception during unit-testing which I cannot
figure
out why it happens. Please help!!
