HI,
If you are only going to have two tables you could ask each table to supply it's selected cell value:

Object value = table.getValueAt( table.getSelectedRow() , table.getSelectedColumn() ) ;

To do this the tables must be visible outside the JInternalFrames
If you want a more flexible model then try adding a MouseAdapter to the tables passing a reference to the owner JInternalFrame in the MouseAdapter constructor and have the mousePressed event pass that reference back to a setSelectedInternalFrame() method which changes a variable in your program so the last JInternalFrame operated on is always known.
Extend the JInternalFrame class and when adding the table create a variable "table" and give it a reference to the table. Include a getTable() method that returns a JTable.
Then the code to get the value would change:

JTable table = selectedInternalFrame.getTable();
table.getValueAt.......etc

Now it doesn't matter how many InternalFrames you have in the future.
P.S.: You might want to consider returning a copy of the table( a new table with the same contents) instead of a reference if you want to protect the integrety of the original table and it's data.
Hope that helps,

hi Terence,
sorry for my misspell your name in my previous mail.
it's working but
when i make a selection in the table in the first frame the second frame is instantiated and works fine.
but when i make another selection in the table in the first frame the second frame is instantiated and displays fine.but when i click the second frame the previous selection retains there,so what should i doto get the value updated.
help is appreciated,
