Почему не получается запустить directoryChooser из JButton

Использую Window Builder в Eclipse. При выполнении следующего кода получаю ошибку.

        });
    }

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().setLayout(null);
        JButton btnOpenFolder = new JButton("Open folder");
        btnOpenFolder.addActionListener(new ActionListener() {

                System.out.println("--- Selected Directory is: " + selectedDirectory);   
            }
        });
        btnOpenFolder.setBounds(12, 217, 175, 25);
        frame.getContentPane().add(btnOpenFolder);
        JList listView = new JList();
        listView.setBounds(34, 13, 361, 47);
        frame.getContentPane().add(listView);
    }
}
