This JSP client allow you to add a new yacht to the yacht club's possession, to remove a yacht, and to
search for yachts that have a capacity over a give number. The name and capacity of the yacht that
meet the searching criteria are listed at the top of the browser screen. By clicking the hyperlink marked
"Destroy," the corresponding yacht is removed from the database. When adding a new yacht, you need
to provide the five persistent attributes of the yacht, namely, yacht name, its builder, the engine type,
capacity, and maximum velocity. An output screen for running this JSP client is illustrated in
Figure 22-1
