How to make hibernate.hbm2ddl.auto=create-drop work?
I have specified hibernate.hbm2ddl.auto=create-drop in my XML. I'm using the H2 database.
I was hoping it would create my table for me. However, I see this on my console when I run a simple test to insert a row in a database.
What am I doing wrong?
Thanks,
Siegfried
