RMI Security Managing Problem

Question

I am trying to connect to my RMI Server and am having a problem. My code looks like this:
if( System.getSecurityManager() == null ) {
                SecurityManager security=new SecurityManager();
                security.checkAccept(serverAddress, serverPort);
              System.setSecurityManager( security );
registry=LocateRegistry.getRegistry(serverAddress, (new Integer(serverPort)).intValue());
                // look up the remote object
                rmiServer= (PRFromDatabaseInterface)(registry.lookup("prFromDBServer"));
                // call the remote method
                System.out.println("Connecting to rmiServr");
                return rmiServer.attemptLogin(email, password);The error I am getting looks like this:
Exception in thread "AWT-EventQueue-0" java.security.AccessControlException: access denied (java.net.SocketPermission 192.168.2.201:3500 accept,resolve)
     at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264)
     at java.security.AccessController.checkPermission(AccessController.java:427)
     at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)
     at java.lang.SecurityManager.checkAccept(SecurityManager.java:1157)
     at us.mylan.pr.main.FromDatabase.<init>(FromDatabase.java:84)Does anyone have any ideas what is wrong?

Answer 1

I Just realized the port wasn't specified. When I do specifity it, I get this error:
sending Sample Text to 192.168.4.204:4000
java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is:
     java.io.EOFExceptionAnd then the server throws a different error:
Exception in thread "RMI TCP Connection(idle)" java.security.AccessControlException: access denied(java.net.SocketPermission 192.167.4.6:54458 accept, resolve)Which I do not understand why it is port 54458. The client code looks like:
public class RmiClient {
    static public void main(String args[])
    PRFromDatabaseInterface rmiServer;
       Registry registry;
       String serverAddress="192.168.4.204";
       String serverPort="4000";
       String text="Sample Text";
       System.out.println("sending "+text+" to "+serverAddress+":"+serverPort);
       try{
           // get the “registry”
           registry=LocateRegistry.getRegistry(serverAddress, (new Integer(serverPort)).intValue());
           // look up the remote object
           rmiServer= (PRFromDatabaseInterface)(registry.lookup("prFromDBServer"));
           // call the remote method
           rmiServer.attemptLogin("[email protected]", "password");
       catch(RemoteException e){
           e.printStackTrace();
       catch(NotBoundException e){
           e.printStackTrace();
