Does Hibernate map object to xml and xml to DB table? That use xml as an intermedia form between object and db instead of directly mapping.

This may sound silly, but in the scenario where object data need to be cached at client location before pushed to the remote DB storage, xml can be the medium used in caching in local file/table, transmission over wire, then transformed to relational DB.

Though normally when converting object to xml, it's serialize/deserialize or xmldom, but since Hibernate already built in the mechanism to map between object and db tables, it would be ideal to generate xml as an alternative.

Thanks for any advice.

No, Hibernate (and no other DB middleware solution I know of) doesn't do this and it would be a really bad idea to use the most verbose text file format for data caching.

I'd like to stress the "caching" here does not necessary mean caching in memory as normally object caching would do. This is in fact a temporary persistence though logically a way to "cache" data at remote location before a message queue transmit it over internet wire. xml can serve as a form to persist the data between locations from distince to guarantee the message delivery.

Alternatively, db tables can be the persistence "medium" instead of xml. However, when it's the time transmit the data, it must be convert to some form of xml as the de facto standard of messaging.

Does HyperJAXB have any functions close enough for this objective?
