Hi:

I am using the Java Persistence API to save entities with Toplink as a
provider.

When I run an RPC service to persist an entity I get the following
exception:

javax.persistence.PersistenceException: Exception [TOPLINK-28018]
(Oracle TopLink Essentials - 2.0 (Build b41-beta2 (03/30/2007))):
oracle.toplink.essentials.exceptions.EntityManagerSetupException
Exception Description: predeploy for PersistenceUnit [AppPU] failed.
Internal Exception: Exception [TOPLINK-30007] (Oracle TopLink
Essentials - 2.0 (Build b41-beta2 (03/30/2007))):
oracle.toplink.essentials.exceptions.PersistenceUnitLoadingException
Exception Description: An exception was thrown while loading class:
com.app.server.Person to check whether it implements @Entity,
@Embeddable, or @MappedSuperclass.
Internal Exception: java.lang.ClassNotFoundException:
com.app.server.Person
// ...

I don't understand why I get such an exception while the Person bean
exists.

Please help me.
