Hint on bean binding a master table to a detail table

It ougth to be * easy to take
two JTables , bind them to a database table and discriminate the
"detail" table on a key.


But it seems nowhere to exist.

as a sample :
jderby-> sample database
  -> customer table ( master)
 -> purchase_orders (detail)
-> key : customer_ID.

task: let the "purchase order" table show the orders assigned to the
selected customer in the customer_table.

It should be drag and drop and visually binding two tables to jtables
and binding two keys to each other.
If bean-binding should have any usage.
