Hibernate version:3.0

Name and version of the database you are using:PostgreSQL 8.0

My question is:

How can i map in hibernate 3.0 beta4 one single value object into 3 tables with same columns as in value object properties.

example:

value object: Document
properties: id, type, Collection of values

tables: Policy, Note, News
columns: id, type

"type" means as dicriminator, where is data persited.
When type = "Po" i want to persist value object into table Policy and so on with others types ("No", "Ne" ).

Reason of this using is large amount of data for one table !

Plz help me, how ... thanks.

I would recommend against this. Pick smaller classes, and aggregate them with one-to-one relationships.

"One big entity" is a bad design, in my opinion. If the data is "too large" for a single database table, its too complex for a well-designed class.

Also, take a look at those tables. Make sure you are not just "breaking out" data, but actually making meaningful groupings. This will make your class design much easier.

I believe I may have misunderstood. You may just need to use subclasses.
