following code

RequestDispatcher dispatcher =getServletContext().getRequestDispatcher("http://localhost:8080/web2/Servlet2");
dispatcher.forward(req,resp);

but it is giving me the error

java.lang.IllegalArgumentException: Path http://localhost:8080/web2/Servlet2 does not start with a "/" character

You can't forward to another application. You can redirect, using sendRedirect()

I would use HttpClient to do that. Basically, making some sort of webservice call.

Hi,

For forwarding request from a servlet to other servlet/resource and including the content of the resources like jsp or html WITHIN THAT APPLICATION can be achieved using RequestDispatcher.
For communicating between 2 applications, you can make use of HttpClient.
