Java security within a browser

Hm... I am pretty new to java. I was pretty much surprised after a couple of days of work to find out that simple

Socket s = new Socket ("somewhere.com", PORT);

doesn't work!!! Neither IE nor Netscape. The latter throws a security exception, and the former one just gets stuck! Don't tell me I can't create a socket when running an applet form a browser?!?!?!

Is there a way to solve this?

You can only open a socket to the machine that has served your applet. That's the rule. So, if your applet comes from A.com, you can't open a socket to B.com.

The only work-around is at the server-side. For example, write a CGI script that opens the stream for you and forward it to your applet.

What are servlets? And how do you make signed applets? CAB files, or something else?
