I get it now. In order to use Hibernate with Derby/Cloudscape, I need to use the “identity” generator:
<class name=”Location” table=”LOCATIONS” schema=”EARTHLINGS”>
<id name=”id” type=”integer”>
<property name=”address” column=”STREET_ADDRESS” />
… other properties …
This makes sense, of course, since in the db build script I have
create table locations (
id integer generated always as identity,
… other column defs …
Now I can use this “earthlings” schema dreamed up by Capstone Courseware in my Hibernate class.
I also stumbled across a NoClassDefFoundError and fixed it by adding a jar file.
I’d say on my list of 10 Canonical Errors (the sequence of challenges I need to overcome to learn any new technology), I’m probably up through 7 now. Getting there.
