Locating Remote Objects - rsanchez-wsu/jfiles GitHub Wiki
RMI provides a "bootstrap name server" to store references to remote objects. The reference can be stored using any of the URL-based methods of java.rmi.Naming.
You must obtain a reference to an object before you can invoke any of its methods. References to remote objects are typically retrieved from a parameter or return value of a method invocation.
