rmi security exception (newbie)

  Asked By: Fabiana    Date: Apr 05    Category: Java    Views: 1981
  

I am just beginning with RMI, and I already have run into
problems. I have tried to start the server and the client.
When I do, I get a security exception. I have followed the
instructions in the tutorial, but to no avail ;(

Here is what I have entered, and found:


C:\rmi>java -Djava.security.policy=java.policy PowerServiceServer
Exception in thread "main" java.security.AccessControlException:
access denied (java.net.SocketPermission 127.0.0.1:1099
connect,resolve)

You can give grant all security  in the policy  file OR a sample policy file as below



grant {
permission java.net.SocketPermission "*:1024-65535",
"connect,accept";
permission java.net.SocketPermission "*:80", "connect";
};
Note: Above, pasted from java.sun.com/docs/books/tutorial/rmi/running.html
Remember, if client  is running on a separate machine, You need a policy for both machines. rmi  claims to download stub files and policy file remotely but it doesn't do this in reality, this leads to such confusions.
