Servlets speak HTTP. All you need to do is open a socket to the servlet
url & port and send a message to the servlet using HTTP protocol.
You can try it out a simple example using a command line. Open a telnet
connection like this:
telnet www.yahoo.com 80
Now enter the following:
GET / HTTP/1.0
and press RETURN twice. The yahoo server sends back the html page that
corresponds to the resource / at www.yahoo.com. This page is the same as
typing http://www.yahoo.com:80 into a browser.
For a servlet, the technique is the same. Open a socket connection to
the servlet url, send the data expected by the servlet, get the response
from the socket.
