public class StubSecurityManager
extends SecurityManager
This class defines the RMI Stub security policy for applications (not applets). For code loaded as a Stub, the security manager disables all functions except class definition and access. To set a StubSecurityManager, add the following to an application's main () method:
System.setSecurityManager(New StubSecurityManager()); If no security manager has been set, RMI will load stub classes only from the local files as defined by CLASSPATH.
