Run the command ipconfig through an applet

Hi!

I am trying to execute the "ipconfig /all" command through an applet; I try to execute exactly these lines:

private final static String windowsRunIpConfigCommand() throws IOException {
Process p = Runtime.getRuntime().exec("ipconfig /all");
InputStream stdoutStream = new BufferedInputStream(p.getInputStream());

StringBuffer buffer= new StringBuffer();
for (;;) {
int c = stdoutStream.read();
if (c == -1) break;
buffer.append((char)c);
}
String outputText = buffer.toString();

stdoutStream.close();

return outputText;
}

but it not working...

Is it something wrong?
May it be that I cannot run a command like "ipconfig /all" in an applet due to security restriction?

Thanks!

Indeed, applets can't use Runtime.exec within the sandbox. There are most likely exceptions to this effect in the Java Console. See HowCanAnAppletReadFilesOnTheLocalFileSystem how to work around this.
