Java RMI AccessControlException: access denied
- by Gwilym
Hey im getting a AccessControlException: access denied when attempting to start up a RMI app im writing, I cant work out why I get this exception if I open it on the default port 1099, or on another dynamic port, my policy file currently grants everything (will change when app is finished).
I am stuck as to where It is going wrong, any help would but of great use
My code
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args) throws RemoteException, AlreadyBoundException, MalformedURLException {
if (System.getSecurityManager() == null)
{
System.setSecurityManager ( new RMISecurityManager() );
}
CreditCardServer ccs = new CreditCardServer();
int port = 1099;
try {
port = Integer.valueOf(args[0]);
}
catch (Exception e)
{
System.out.println("Invlaid Port");
}
if (((port <= 65535) && (port >= 49152)) || port ==1099)
{
System.out.println("Valid Port");
}
else
{
port = 1099;
System.out.println("Port not in Dynamic Range 49152<-->65535");
}
System.out.println(port);
LocateRegistry.createRegistry(port);
LocateRegistry.getRegistry().bind("CreditCardServer", ccs);
while (true)
{
//hum?
}
}
}
