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.

In app-x, we write

ServletConfig config=getServletConfig();
ServletContext context application=config.getServletContext();
ServeltContext anotherapp=application.getContext("/app-y");

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.

What exactly do you mean by communication? Do you have data or objects that you would like to share between both? Or do you want to send messages from one to the other?

If that's all you need to do, it should be as simple as posting from one app to the other by setting your HTML form's attribute value to point to the other app.
