Hello,

I generate the database schema from the mappings using the Ant SchemaExport task.

To be cross-platform I have picked the native id generator as suggested by the Hibernate reference.

According to the documentation "native" means that Hibernate will pick the identity, sequence or hilo algorithm depending upon the underlying database.

Everything works fine with PostgreSQL but if I switch to HSQLDB, schema generation fails with "could not instantiate id generator". Any idea what is wrong?

Best regards,

Peter
