///////////////////////////////////////////////////////////////
// This is a sample policy file that grants the application all permissions. 
// A policy file is needed by the RMISecurityManager and your application might
// not work after installing the RMISecurityManager unless you provide a 
// security policy file at launch.
//
// You can configure the security policy of a launched application using either
// the RMI Launcher or by manually setting the java.security.policy property.
//
// SECURITY NOTE: This security policy is good for development. For deployment
// you may need a stricter security policy.
