Aah, thanks for the clarification. I didn't notice your earlier message
on the topic.

Given that, it's pretty clear that the OP has to fix their app to:

- Trust Hibernate to generate their DDL, taking care of their db
portability issues;

- Use per-database DDL with the data types Hibernate expects;

- Use a short in Java if they want a short in the database, and convert
it in their accessor methods; or

- Use a Hibernate UserType to call the appropriate set() and get() JDBC
methods, overriding the default type-based options in the dialect.
