This is just a general query, regarding whether this can be done or not ?

My question is Can a POJO class be created that can refer to different tables at different times.

Eg object of class "Address" which can refer to "PersonAddress" (table) when an object of "Address" type is stored in "Person" class (a table also exists by the name Person ), and when an "Address" reference is stored in say "Organization" class (a table also exists by that name) then it has data from "OrganizationAddress" table.

Hai.
I would really like to help you. but if you can please rephrase your last two lines, I'd be happy. I cannot understand. Sorry for the trouble.

Ok to make that even simpler...

There is a class named Address { String line1,line2,city,state;}

Now i also have a POJO named Person and Organization.
Person and Organization can both have multiple addresses just like you can have many residences and the way my company has many offices :-)
The Person class has a reference of Address type in it





All addresses related to Person are stored in table PersonAddress and addresses related to Organization are stored in table OrganizationAddress.
Both PersonAddress and OrganizationAddresses store same columns.

So is it possible that I use only 1 datatype of Address POJO instead of using two seperate Hibernate POJO's for PersonAddress and OrganizationAddress ?

use inheritance with 'table per class' strategy.
a) base class: address, the rest inhertis from them.
b) and as you want two DB tables, choose 'table per class'

i will try that ... i think that would work ...

Exactly.
Do as 'tbech ' suggested.

try using this clause "<joined-subclass>". :-)
