Modified: web/example tour.htm
Log:
Remove references to the database servlet saving changes to the in-memory
pseudo database, since this functionality no longer exists. (There is no
portable way to save and reload this data, and the whole point is to
illustrate Struts programming principles, not how to fake out a database).

<p>In addition to the usual getters and setters, the user object also has two
methods for working with subscription objects. findSubscription takes a hostname and
returns the subscription object for that host. getSubscriptions returns an array of
all the
subscriptions for the user (ready-made for the iterate tag!). Besides the fields
needed to manage the SubscriptionForm data, the object also maintains a runtime link
to its user object.</p>

permanent storage solution, so all the changes won't be lost if the application ever
terminates abnormally. </i></p>

Saving the best for last, subscription.jsp demonstrates use of some interesting
Struts custom form tags, html:options and html:checkbox.
