The presence of the stereotype allows for the servlet to be represented in a compact form and still be easily distinguished as a generic servlet without the need to show the inheritance tree on the same diagram. A generic servlet can include any of the life cycle methods or the convenience method discussed earlier.

A more expanded view of the servlet class showing the inheritance from the GenericServlet class can also be used. In most cases, though, the more compact stereotyped class view is sufficient. The compact and expanded representations of the servlet are shown in Figure 10-5.
