When I try to start our application in TPTP, I get the following exception
from TopLink:
Exception in thread "main" javax.persistence.PersistenceException:
Exception [TOPLINK-28018] (Oracle TopLink Essentials - 2.0 (Build 41
(03/30/2007))):
oracle.toplink.essentials.exceptions.EntityManagerSetupExcep tion
Exception Description: predeploy for PersistenceUnit [FoobarPU] failed.
Internal Exception: Exception [TOPLINK-7150] (Oracle TopLink Essentials -
2.0 (Build 41 (03/30/2007))):
oracle.toplink.essentials.exceptions.ValidationException
Exception Description: Invalid composite primary key specification. The
names of the primary key fields or properties in the primary key class
[com.xxx.entities.FoobarPK] and those of the entity bean class [class
com.xxx.entities.Foobar] must correspond and their types must be the same.
Also, ensure that you have specified id elements for the corresponding
attributes in XML and/or an @Id on the corresponding fields or properties
of the entity class.

TopLink gives this exception for all our entities which use composite
primary keys. However, the application runs fine without TPTP, and also
using Eclipse's debugger.
If I use EclipseLink 1.0.1 libraries the application also works with TPTP,
however we have to use older Toplink libraries.
Do you have any ideas what could cause this incompatibility?
