Hello Ladies and Gentlemen,
I need your help please.
Storing the following data structures to the data base keeps ending up in a
NullPointerException no matter what I try.
BenutzerBO <- m:n -> PrivilegeBO - 1:n -> ActionBO
My configuration:
OJB 1.1 rc3.
MySQL 3.23.52 (as shipped with Suse-Linux 8.1)
Java 1.4.1
Stack-Tace:
[org.apache.ojb.odmg.ObjectEnvelopeTable] ERROR: Commit on object level
