Hi Lakshmi, it is quite simple.In order to esablish communication between two web applications running in the same web container,we use RequestDispatcher.forward() method. For Ex app-x and app-y are two web applications running in Tomcat.
using anotherapp ref we can access the objects in app-y application. We can use rd.forward() to forward to the resource available in another web application. [ February 10, 2007: Message edited by: Janakiram Gattupalli ]
