Thank you Greg I have found the docs on schema files.
For what it worths, I will put my 2 cents on the Torque vs Hibernate matter.
Usually you don't want to overwrite your sql if you are not in the early
steps of db development: you change the DDL saving the data in some way.
The utility of software like torque is greater when you are in an
advanced stage of development and it saves a loto of time in modifying
java code.
Then, given your answer about the limitations of the jdbc task, I think
that the absence of some visual tool that is able to produce this schema
files is something  that prevents Torque to be more successful.
For example if Power Architect would be able to generate both the schema
file and not only the sql it would be great.
