Vasu,
You can use RequestDispatcher(URL).forward(req,res) for servlets
communication within the same server.
For cross servers, if you want the servlet 1 to finally send a response to
the client after getting the response from servlet2 you may use URL
Connection to write to the connection. Read the input stream in servlet1 and
send an appropriate response to the client.
If you wish to pass on the control from servlet1 to servlet2 use
Response.send Redirect(). From thereon the servlet 2 can process and send
the response to the client.
good luck :-)
