Trail: Servlets
Lesson: Interacting with Clients

## Providing a Servlet Description

> Some applications, such as the Java Web Server Administration Tool, get descriptive information from the servlet and display it. The servlet description is a string that can describe the purpose of the servlet, its author, its version number, or whatever the servlet author deems important.

> The method that returns this information is `getServletInfo`, which returns `null` by default. You are not required to override this method, but applications are unable to supply a description of your servlet unless you do.

> The following example shows the description of the BookStoreServlet:

>         public class BookStoreServlet extends HttpServlet {
>             ...
>             public String getServletInfo() {
>                 return "The BookStore servlet returns the " +
>                        "main web page for Duke's Bookstore.";
>             }
>         }
