Java Enterprise in a Nutshell, Second Edition

Name

ServletResponseWrapper

Synopsis

A convenience method that can be used by filter developers to modify the behavior of a ServletResponse object. The default implementation of each method calls through to the original ServletResponse object, and methods can be selectively overridden to provide additional functionality. ServletResponseWrapper objects can also be used in calls to the forward() and include() methods of RequestDispatcher.
