hello
i write a simple interface "Hello.java",i want to call it by rmi,after "javac","rmic","rmiregistry",i want to start "RMIServer.class" that is used to register in the server,see my code:

==================================================
public
class RMIServer{

private static final int PORT=1099;

private static final String
HOSTNAME="127.0.0.1";


public RMIServer()

throws RemoteException,

MalformedURLException,

NotBoundException{


LocateRegistry.createRegistry(PORT);

System.out.println("registry:"+HOSTNAME+" in "+(Integer.toString(PORT)));

Hello h=new HelloImpl();

System.out.println("remote object has be created");

String urlString="//"+HOSTNAME+":"+Integer.toString(PORT)+"/HelloService";
Naming.rebind(urlString,h);

System.out.println("binding finished");

}


public

static

void

main(String argv[]){

System.setSecurityManager(new RMISecurityManager());


try{

RMIServer rs=new RMIServer();

}catch(Exception e){

System.err.println(e);

}

}

=================================================


i type"java RMIServer",it tell me:


==================================================
java.rmi.server.ExportException: Port already in use: 1099; nested exception is:


java.net.BindException: Address already in use: JVM_Bind

==================================================


then i modify the port number to "10002",it said:


==================================================

registry:127.0.0.1 in 10002
remote object has be created

java.security.AccessControlException: access denied (java.net.SocketPermission
127.0.0.1:10002 connect,resolve)

==================================================


who can tell me why?

thanks alot
