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.
