What do you mean by "activate one applet by pushing a button in another applet"?  Do you want to load a page with the second applet when you push a button on the first applet?  In this case, you need to use this syntax:

this.getAppletContext().showDocument("url")

where url is the url of the page with the second applet.

As to CGI, there are two ways you can do it.  If it's a GET cgi, you can use the same syntax:

this.getAppletContext().showDocument("cgi-url?param1=val1&param2=val2...")

param=val strings should be url-encoded (e.g. " " changed into "+", and so on).  If you want to activate the POST cgi, you need to establish connection to the server through sockets and send the request in the form:

   POST /path/cgi-name HTTP/1.0
   Connection: Keep-Alive
   User-Agent: Mozilla/4.05 [en] (Win95; I)
   Host: www.cmscience.com
   Content-type: x-form-urlencoded
   Content-length: <length of your parameters string>
   Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png, */*
   Accept-Language: ru
   Accept-Charset: iso-8859-1,*,utf-8

   param1=val1&param2=val2...  (this is your parameter string).

Each line should end with "\r\n", not simply "\n".  The whole thing should be followed by "\r\n\r\n".  The problem with this method is that you're going to get back the html text output by the cgi program/script - you'll need to think of a way to display this html back into the browser.

Hope this helps,
-Aleks.

Thank u for your answer!
I still have a problem (I'm just a beginner in Java...)
I want to activate an applet, that it's location is the same as the applet that activaed it: on the same directory, on my computer. As the matter affect: It's like trying to execute a program. All I have is the applet name and it's class file. And I want that by a press of a button, this class file will be executed!
