Figure 22-3. BuzzInServlet in action
The game show host has access to an HTML form with a POST method, which calls the
doPost()
method. This displays the winner to the game show host and resets the “buzzer”
for the next question. A password is provided; it's hardcoded here, but in reality the pass-
word would come from a properties file (
Storing Strings in Properties and Preferences
)
or a
servlet initialization parameter (as described in
Java Servlet Programming
[O'Reilly]):
