Get the response instead of loading it in the browser

Question

HI.
I would like to make a little program that would read the response of a request to a web page. I'm cant find how to do it. Everything i can foud call's the URL but loads th result in the initial browser window.
Heres what I want :
1- A friend as a servlet on a web site that does some maths with initial numbers intered in the window.
2- I would like to make another servlet that would send some numbers to my friends servlet on the url(GET method).
3- The all purpose is to be able to send a series of request on is servlet from a little list of numbers.
I would appreciate any inputs. I've looked thru the javax.servlet.http librairis and java.net.
Thanks for helping me.

You don't need a servlet, an ordinary jaav program can do this. Have a look at the java.net package in the JDK docs. Something (totally untested!) like this should work;
URL url = new URL("http://www.friendssite.com/friendsServlet?par1=val1&par2=val2&par3=val3");
//par and val are as required by your friends serlet
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
con.setRequestMethod("GET");
conn.connect();
InputStream in = conn.getInputStream();
//Now you can read the results from the InputStream
