Java applet open network sockets?

Question

So i made this simple JApplet and tried to open a socket and write to it, but i got an exception saying i don't have permission???

So then i looked at this: http://java.sun.com/developer/onlineTraining/Programming/JDCBook/signed.html

I've got the jar signed, and that's it. I don't get what to do after that????

And in the html file, what does

<param name=file value="/etc/inet/hosts">

do?

Are there any easier ways to sign japplets?

Let me ask this simply. How do i let my applet open a socket on lets say port 80 for google.com?

Answer 1

<param name=file value="/etc/inet/hosts">

This means that the name 'file' will have the value /etc/inet/hosts when queried by the applet. EG

// in the init() method ..
String fileValue = getParameter("file");
// fileValue now has the value '/etc/inet/hosts'
