Polyhedra is a Real Time RDB and we are looking for anyone who has used it with Hibernate. What we are looking for is someone or some forum that can answer the following questions.

1. Polyhedra does not have the standard notion of a transactions. Polyhedra does not support the execution of multiple Statement.executeUpdate() or Statement.executeBatch() commands followed by a commit or rollback. Instead, one can only execute a single Statment.executeBatch(0 (it can have a lot of sql statements) which must be immediate followed by a commit or rollback. How do we use/tweak Hibernate to work with this transaction model.

2. Polyhedra does not fully support the JDBC metadata API. We don't have all of the details just yet. Does Hibernate absolutely require the metadata API?

If this is not the right place to ask this question, please point me to the right place.

Regards,

David Glaser
