RMI Security Exception

Question

Hi I have followed the sun java RMI trail (tutorial).
However my server side application is giving me a security exception. I think it s because of the grant code sections:
grant {
    permission java.net.SocketPermission "*:1024-65535",
        "connect,accept";
    permission java.net.SocketPermission "*:80", "connect";
};My problem is that I can't understand were to put this code segment, and I read the same page over and over again, and could not find were is says were to put it!!
As I said I think it is from this, but maybe it is from other parts! not sure! ... Maybe you need to run the server side from a web server??
The links of the tutorial I am following is the following (from sun java website itself):
http://java.sun.com/docs/books/tutorial/rmi/
and the following link is were there is the grant permission code:
http://java.sun.com/docs/books/tutorial/rmi/running.html
Thanks for any sugestions!

Answer 1

I still have the exception:
ComputeEngine exception: access denied (java.net.SocketPermission host resolve)
java.security.AccessControlException: access denied (java.net.SocketPermission host resolve)I followed the tutorial step by step, reading and writing the provided code so far. So this is what I have now at the moment:
I create a permision file and I called it java.policy. In this file I have the following code:
grant {
    permission java.net.SocketPermission "*:1024-65535",
        "connect,accept";
    permission java.net.SocketPermission "*:80", "connect";
};Then I have the following code sugested by WirajR in the engine class, which is the server side application:
static{
    System.setProperty("security.policy", "java.policy");
}I compiled everything, and no errors are given. But when i run just the server side, I still recieve the above error. When I debuged the application it stops on the following line:
Naming.rebind(name, engine);Were name is a string containing the following text :
"//host/Compute"and engine is the class to be exposed over RMI.
I am betting my problem is with name!! ... maybe
or else my permission file has invalid data.
Also wanted to add that security seems to have been taken care of in that tutorial by the following lines of code:
if (System.getSecurityManager() == null) {
   System.setSecurityManager(new RMISecurityManager());
}Aren't these to set the security policy?
