I have an application that logs events to a history table, and my clients want some of the event fields to be saved into their existing DB schema, which has the fields spread out across several different tables.

Is it possible to configure Hibernate to store individual fields of a class in different tables without creating a separate class to contain those fields? It would be nice if I could just configure the hibernate mappings to point the fields to these tables. I don't think its possible; at least I'm not sure how you could map to the correct row in the existing table.

Any input appreciated,

Thanks

No this is currently not possible. It might be introduced in 2.2 with the <join> element.
