The original posting asked if there are two database
on two machine. The have the same table, same column
and posibaly, some data have the same PK value.
When I said *one* table, I mean: not two.
If I had twin sons, I would name them differently.

Entity Bean representes a piece of data in *one*
database. If you have two database, even there
the table name, column name and primary keys are
the same, they are different pieces of data. They
can not be represented by the same bean.
