Hello;
I am experiencing a problem. I am trying to retrieve PersonalCustomer from
DB2. PersonalCustomer extends Customer and each have its own tables in DB2.
I am able to retrieve Customer successfully. I am able to retrieve
PersonalCustomer too when I remove the inheritance hierachly both in code
and Castor mapping file. But when PersonalCustomer extends Custoemr and
declare this using "extends" keyword in Castor mapping file I am receiving
following exception when I call hasMore() on result set object:
java.lang.NullPointerException

Exception in thread "main"
Weird thing is that my code successfully runs on Oracle. I believe the
problemis with DB2 or its driver.
DB runs on NT and I use "COM.ibm.db2.jdbc.app.DB2Driver".
Any idea?
Best regards,
