Thanks so much for the reply. Based on your remarks, I think I've figured
out what's going on.
Some tables in my schema have underscores in the table name, while others
do not. If there ARE underscores in the table name, the mapper includes
the @Table annotation, and the class name is set to the actual table name
with no underscores.
Most tables in my schema have underscores in the column names. But for
the few columns that don't have underscores, there is no @Column
annotation provided.
