            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));
            jPanel.add(new JLabel(i+" :label 2"));

            jTabbedPane1.addTab("tab", jPanel);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }                                     
    public static void main(String args[]) {

        java.awt.EventQueue.invokeLater(new Runnable() {

            public void run() {
                new ChatDialog_Tabbedpane().setVisible(true);
            }
        });
    }
    // Variables declaration - do not modify
    private javax.swing.JButton jButton1;
    private javax.swing.JScrollPane jScrollPane1;
    private javax.swing.JTabbedPane jTabbedPane1;
    private javax.swing.JTextArea jTextArea1;
    // End of variables declaration
}

Don't use add with JScrollPane, use setViewportView instead, for example...

jsp.setViewportView(jPanel);

See How to Use Scroll Panes for more details

A component may only reside within a single contaniner, when you do something like...

jTabbedPane1.addTab("tab", jPanel);

You are removing the jPanel from it's previous parent (the JScrollPane), instead, add the scroll pane to the tabbed pane...

jTabbedPane1.addTab("tab", jsp);
