| 30 | /** | ||
| 31 | * A subclass of {@link SecurityManager} used by RMI applications that use | ||
| 32 | * downloaded code. RMI's class loader will not download any classes from | ||
| 33 | * remote locations if no security manager has been set. | ||
| 34 | * <code>RMISecurityManager</code> does not apply to applets, which run | ||
| 35 | * under the protection of their browser's security manager. | ||
| 36 | * | ||
| 37 | * <code>RMISecurityManager</code> implements a policy that | ||
| 38 | * is no different than the policy implemented by {@link SecurityManager}. | ||
| 39 | * Therefore an RMI application should use the <code>SecurityManager</code> | ||
| 40 | * class or another application-specific <code>SecurityManager</code> | ||
| 41 | * implementation instead of this class. | ||
| 42 | * | ||
| 43 | * <p>To use a <code>SecurityManager</code> in your application, add | ||
| 44 | * the following statement to your code (it needs to be executed before RMI | ||
| 45 | * can download code from remote hosts, so it most likely needs to appear | ||
| 46 | * in the <code>main</code> method of your application): | ||
| 47 | * | ||
| 48 | * <pre> | ||
| 49 | * System.setSecurityManager(new SecurityManager()); | ||
| 50 | * </pre> | ||
