CMP newbie question
I am trying to get a basic CMP bean to work.
When I try to lookit up using the findByPrimaryKey(), I get a
FinderException: No Such Entity!.
error message
I am sure I am doing something stupid, or completely forgot something.
I am using JBoss 3.2.1 with Oracle as the datastore. I turned on the tracing (in log4J),
and the SQL select statement generated by the finder method seems okay.
Not sure where else to look.
Any suggestions would be aprreciated.
