This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
In Column a1b1 of Table C we are storing the values from PK Column a1 from table A or PK Column b1 from Table B. i.e, some rows in Table C relates to Table A and some relates to Table B depending on this Column "a1b1" column value. Please help me in doing the mapping for this case in JPA Annotations.
I have used below mapping that was NOT working.
