Servlet 4.0 Mapping Discovery Introduction
Every mapping that causes a Servlet to be activated, regardless of whether or not Servlet Filters are involved,
is discoverable at runtime via the Servlet Mapping API. This feature allows runtime discovery of the manner
in which the HttpServlet for the current HttpServletRequest was invoked. Invoking
any of the methods must not block the caller.
The method getHttpServletMapping() on HttpServletRequest returns an
HttpServletMapping implementation that provides information for the mapping that caused the current
Servlet to be invoked.
As with the included and forwarded request parameters, the HttpServletMapping is not available
for servlets that have been obtained with a call to ServletContext.getNamedDispatcher().
Description of the Example
This example demonstrates how to use Servlet Mapping API at runtime.
This example has two Servlets, ServletA and ServletB. The following
hyperlinks explore the various values for the properties of HttpServletMapping,
depending which Servlet is invoked and with what path.
