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 returnsnull
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."; } }
