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)
{
}
}
}

I am newbie in J2EE & looking for strong basic behind each concept as, Why do we use private access specifier before each variable of type property bcoz ultimately to access it outside the class we use public method as getter & setter ? If we use getter & setter to access it outside the class so better we make variable as public so that it is easily available outside of the class... Please guide me why do we use as private ????
