Class java.rmi.RMISecurityManager

public class RMISecurityManager
extends SecurityManager
RMISecurityManager provides a default security manager for use by RMI applications that need one because they use downloaded code. RMI's class loader will not download any classes if no security manager has been set. RMISecurityManager does not apply to applets, which run under the protection of their browser's security manager.

To set the RMISecurityManager, add the following to an application's main() method:

 System.setSecurityManager(new RMISecurityManager());

The RMISecurityManager follows the same policy as the java.lang.SecurityManager class for security check methods that it does not override.

Since:
JDK1.1
