Re: [eclipselink-users] Physical table name derived from a property

For a single persistence unit/session a class can only map to a single table. 
I would recommend you consider having two subclasses for each table.

You could also have two different persistence units/session that each map
the class to a different table.  You could also map the class to a view, and
use triggers in the view to decide which table to write to.
