Re: Eclipselink with Spring 2.5.6 and Weblogic 10.3

Could you include the full exception stack trace.

Also try enabling logging to finest and see was is logged ("eclipselink.logging.level"="finest" in persistence.xml). Maybe also try deploying your persistence unit outside of Spring to see if it is a Spring issue.

Hello,

I'm having some issues trying to get eclipselink to work with my
application... I saw this e-mail address on a help-site, so I'm hoping
this will be an okay place to start... Whenever I attempt to run an
web-app, I get the following error:

Could not obtain JPA EntityManager; nested exception is
javax.persistence.PersistenceException: Exception [EclipseLink-28019]
(Eclipse Persistence Services - 1.0.2 (Build 20081024)):

I figure it's something with either my application-context.xml OR my
persistence.xml, I just don't know what... Any ideas???

Application-Context.xml:

Any help is REALLY appreciated, I'm truly at a loss as I'm fairly new to
