Use data from a frame to another

Question

Hi,
I would like use the data from my first frame in DataPanelCli in my second frame StruCliBox.
BUT when I writte text in my first frame, and I use the button structcli in the ButtonPanelCli, it is always blank in my second frame.
What have I to do.
regards.

a Q&D, note the static DataPanelCli's ICCliFact.
class DataPanelCli extends JPanel {
static JTextField ICCliFact, INSociete;
class StruCliBox extends JPanel {
ICCliFact = new JTextField( 20);ICCliFact.setText( DataPanelCli.ICCliFact.getText() );
