RequestDispatch is mainly used to shipping request
attributes from one servlet/jsp to another servlet/jsp.
While doing this we first create RequestDispatch instance
with string url as parameter to where request data to be
shipped. Then we cal reqDispatchReference.forward
(request,response) method. This is something like assigning
work to third party.
Ex:(to forward request data from Servlet1 to page2.jsp)
class Servlet1 extends HttpServlet{
public void service(... request,... response){
...........
RequestDispatcher rd=request.RequestDispatcher("page2.jsp");
try
{
rd.forward(request,response);
}
catch(Exception e)
{
}
}
}
