RMI Structure by Yoonju Kim RMI is implemented as three layers between the application program and the Java virtual machine. Stub program in the client side and a corresponding skeleton at the server The stub appears to the calling program to be the program being called for a service. (Sun uses the term proxy as a synonym for stub.) Remote Reference Layer It can behave differently depending on the parameters passed by the calling program. For example, this layer can determine whether the request is to call a single remote service or multiple remote programs as in a multicast. Transport Connection Layer It sets up and manages the request. A single request travels down through the layers on one computer and up through the layers at the other end.
