Java APIs

Hi there,

I am trying to get the RMI tutorial (http://java.sun.com/docs/books/tutorial/rmi/index.html) to work with ClassFileServer (http://java.sun.com/javase/technologies/core/basic/rmi/class-server.zip) as mentioned in the tutorial. The ClassFileServer was instantiated inside the RMI server instead of running one separately. I am currently having a problem with understanding a policy file as I am a newbie in this area. I could get the server running using the following server.policy:

grant codeBase "file:home/ann/src/" {
  permission java.security.AllPermission;
};
grant codeBase "file:/home/ann/public_html/classes/class-server.jar" {
  permission java.security.AllPermission;
};

But as soon as I replace the above with below, I got the following error:

java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:{port number} accept, resolve)

grant codeBase "file:home/ann/src/" {
  // The following is needed for name rebind...
  permission java.net.SocketPermission "localhost:1099", "connect, resolve";
};
grant codeBase "file:/home/ann/public_html/classes/class-server.jar" {
  permission java.security.AllPermission;
};

Error stack trace indicated that the following line in ClassServer causes the problem:

socket = server.accept();

My question is why this is possible as I have given all classes in the class-server.jar (ClassServer resides in this jar file) all access to everything (as indicated by line 'permission java.security.AllPermission').

Second question is: how then should the correct server.policy file look like? Any help would be greatly appreciated.
