Checking the value returned by getParameter is a common solution to
determining which button was selected in the form. One drawback is that
if someone wants to change the text displayed on the button face, the
servlet must be recompiled. A better solution is to check that the
return value is non-null, rather than checking that the return value
equals some String. Just remember to give each button in the form a
unique name.
