• RMI provide dynamic method invocation. A client can invoke a server without knowing which methods are contained in server.
• The Remote Reference is responsible for determining the nature of the object. Is it local or remote? If remote, will it start automatically or does it need to be initialized?
• Java remote objects are platform independent, but you must use Java at both ends (if you ignore rmi-to-corba-dcom bridges).
• Remote objects are garbage collected using reference counting.
• The RMI registry provides access to remote objects.
