I have problems with security in my applet, which should send data between
two PC in a local network. I have tried something like this:
Socket server = new Socket("101.0.0.1",1234);
OutputStream out = server.getOutputStream();
out.write(13);
server.close();
and this in the server application:
ServerSocket listener = new ServerSocket(1234);
while (true){
Socket aClient = listener.accept();
InputStream in = aClient.getInputStream();
int zahl = in.read();
}
The problem is the SecurityManager which seems to refuse to open a socket
(he does not if I start my Applet from an IDE, as J++) and a
SecurityException occurs.
What is the easiest way to manage this. I have read about signing applets,
creating keys, etc. in documents from sun.com, but it looks quite difficult
and nothing really works (it seems so!).
Thanks,
Stefan, cerasus@gmx.de
