Adding Table to Frame generates: 'javax.swing.JPanel' has no attribute '__call__'

Reading through the book "Python Programming with the Java Class Libraries" I entered the code on page 417 and got the following results.  What might be causing the error?

 

>>> from javax.swing import JFrame, JTable

>>> frame = JFrame('this is a table test')

>>> table = JTable(4,4)

>>> frame.contentPane().add(table)

Traceback (innermost last):

  File "(console)", line 1, in ?

AttributeError:  instance of 'javax.swing.JPanel' has no attribute '__call__'
