Hi, I'm using EclipseLink JPA provider only (eclipselink.jar) and I need
to use

org.eclipse.persistence.jpa.PersistenceProvider.createContai nerEntityManagerFactory

for some reasons. I'm implementing sorts of server services, so I can't
use persistence.xml because of conflict with applications.

But while calling
org.eclipse.persistence.jpa.PersistenceProvider.createContai nerEntityManagerFactory,

I met this excetion from it,


javax.persistence.PersistenceException: Exception [EclipseLink-28018]

I guess PersistenceProvider.createContainerEntityManagerFactory presumes
there exist SDO libraries. (maybe moxy libs, too)

But I don't need SDO... and it may be a burden to add SDO libraries only
for this...

Is there any property started with "eclipselink." to turn off sdo library
search?

That is odd, it looks like it is trying to load
org.eclipse.persistence.sdo.SDOResolvable to see if it is an Entity. Did
you add this class in your persistence.xml, or did you include the
eclipselink.jar in your persistence.xml? That is incorrect, the jars tag
in the persistence.xml is only for your application classes, it should not
include libraries of eclipselink.jar.

Please include your persistence.xml if still having issues.

Thank you for your reply.

As I said, I'm using programmatic EntityManagerFactory creation with
javax.persistence.spi.PersistenceProvider#createContainerEnt ityManagerFactory,
not using persistence.xml.

I found a cause of my problem.
I made my
javax.persistence.spi.PersistenceUnitInfo#excludeUnlistedCla sses()
implementation return 'true'
and then exception had disappeared.

Eugene,
That solution will work, but it looks like you may be including the
eclipselink jar in your EAR where the EMF will search for entities without
the [excludeUnlistedClasses] override (it defaults to false on an EE
container) - it may be searching the entire implementation jar. I would
verify where you are placing the EclipseLink library on your classpath and
recommend putting it higher outside of your EAR on the server's shared
library folder.
thank you
/michael
