/**
|
|
* {@code RMISecurityManager} implements a policy identical to the policy
|
|
* implemented by {@link SecurityManager}. RMI applications
|
|
* should use the {@code SecurityManager} class or another appropriate
|
|
* {@code SecurityManager} implementation instead of this class. RMI's class
|
|
* loader will download classes from remote locations only if a security
|
|
* manager has been set.
|
|
*
|
|
* @implNote
|
|
* <p>Applets typically run in a container that already has a security
|
|
* manager, so there is generally no need for applets to set a security
|
|
* manager. If you have a standalone application, you might need to set a
|
|
* {@code SecurityManager} in order to enable class downloading. This can be
|
|
* done by adding the following to your code. (It needs to be executed before
|
|
* RMI can download code from remote hosts, so it most likely needs to appear
|
|
* in the {@code main} method of your application.)
