Re: nested exception is
org.apache.openjpa.persistence.Entity NotFoundException
Hi,
As you are seeing the application work with another JPA implementation, I
assume that the instance of org.apache.camel.example.etl.CustomerEntity with
id 100 does really exist in database and not actaully deleted by another
transaction. Assuming that the actula record exists but OpenJPA somehow
fails to load it from database (yes, the stack trace shows that OpenJPA is
trying to load it from the database), one way to narriw down further is to
squeeze out the SQL issued by OpenJPA to find the instance before it failed.
