From your applet  u can;
.................
URL url = new
URL("http://<host>/<servlet>?<query>");
......................
...url.openStream()...
......................

:do not forget that unsigned applets  can only connect
to hosts where they had been downloaded.

Yes, you can use applet  and servlet  together. I had used. Let me know
your requirement so that I can send you the sample code.

I will make an applet  which has some basic information, mainly some
numbers that i would like to be stored on a database  on the server.
I want the servlet  to somehow extract those numbers and send them to
the server via servlets... will i be able to do vice-versa, i.e.
retrieve infomation from the server to the applet??
