Hi,
First of all, I apologize for this late answer;
I was out of my office for several weeks.
Have you resolve your problem ?
It seems there is mixing up with long and java.lang.Long.
If the 'roleID' attribute is defined in the deployment descriptor
as the primkey-field, it must be declared java.lang.Long instead of
java primitive type 'long'.
Hope this help you.
Regards.
H�l�ne.
