there should be a few ways to work around this -- I've
dealt with it before using a custom NamingStrategy and
an extended Dialect (for mysql). 

For example, if you want mysql to treat a schema name
as if it were a catalog, you can subclass MySqlDialect
and return '.' instead of '_' in the
getSchemaSeparator method. 

We use a NamingStrategy to substitute schema names
retreived from configuration at runtime to get our
full table names.

Not sure exactly what you're trying to do but if you
want to point me to the code you're working on I could
try to help out.
