What is Request Dispatcher and What is reuest Processor??

Answer

RequestDispatcher is an interface
which is used to forward our request to java
enabled Resources like servlet,jsp.. within the server.
it has one limitation i.e we cant forward req to
outside server... that was achieved by using sendreDirect
mechanism ..which forwards request not only within the
server but also outside servers.

RequestProcessor is an predefined class given by structs
framework..
and it is helper class to Structs controller
component i.e ActionServlet by using the method process()..
eventhough it is predefined we can create our
own RequestProcessor class
