What is the use of RequestProcessor, if we are having ActionServlet in struts..

Answer / nitilaksha m shetty

The RequestProcessor is a helper class instantiated and used
by ActionServlet to process each request that comes in. The
RequestProcessor actually does most of the work involved
when a request comes in and a response goes out. The
ActionServlet(org.apache.struts.action.ActionServlet) is
invoked each time an incoming HTTP request is received. It
then calls the
RequestProcessor(org.apache.struts.action.requestProcessor)
to determine which form bean to instantiate and which action
class to call based on the contents of your
struts-config.xml file.

Answer / himanshu

The RequestProcessor is the class that we need to override
when we want to customize the processing of the ActionServlet.
It has a predefined entry point that is invoked by the
Struts Controller with each request.The entry point is the
processPreprocess method.

Answer / arundhathirockon

The RequestProcessor of Struts 1.2 'll act as a controller.
and the ActionServlet is used to communicate the server and
RequestProcessor. We 'll use the ActionServlet for
serverside communication.
