The
Order
object encapsulates the order and its status, and it will be passed between the applet
and servlet.
The
OrderStatusApplet
The
OrderStatusApplet
will leverage some of the Java Swing classes that are bundled with
the JDK 1.1.6. You do not need to concern yourself with all the swing classes. The only two
you need to understand are the
JTextField
and
JTextArea
classes. The
JTextField
will hold
your order number, and the
JTextArea
will display the returned status. Listing 6.6 contains the
source for the client applet.
