Stub and skeleton layer in rmi guides: >> http://ivs.cloudz.pw/read?file=stub+and+skeleton+layer+in+rmi+guides << (Read Online)
The RMI system consists of three layers: The stub/skeleton layer -- client-side stubs (proxies) and server-side skeletons; The remote reference layer -- remote reference behavior (such as invocation to a single object or to a replicated object); The transport layer -- connection set up and management and remote object
Described in the implementation language: 1st class RMI Remote Procedure Call. (RPC) et al. Java Remote Method Invocation. (Java RMI) Stub/Skeleton Layer. ? Stub. ?Has same interface as remote object. ?Initializes call to remote object. ?Marshals arguments to stream. ?Passes stream to remote reference layer.

RMI uses a standard mechanism (employed in RPC systems) for communicating with remote objects: stubs and skeletons. A stub for a remote object acts as a client's local representative or proxy for the remote object. The caller invokes a method on the local stub which is responsible for carrying out the method call on the
Stub and Skeleton layer. Intercepts method calls made by the client to the interface reference variable and redirects these calls to a remote RMI service. 2. Remote Reference Layer. Interpret and manage references made from clients to the remote service objects. 3. Transport layer. Is based on TCP/IP connections between
The Stub/Skeleton hides the communication details away from the developer. The Stub is the class that implements the remote interface. It serves as a client-side placeholder for the remote object. The stub communicates with the server-side skeleton. The skeleton is the stub's counterpart on server-side. Both communicate
The stub/skeleton layer is the interface between the application layer and the rest of the RMI system. This layer does not deal with specifics of any transport, but transmits data to the remote reference layer via the abstraction of marshal streams. Marshal streams employ a mechanism called object serialization which enables
Jul 8, 2008 RMI makes remoting transparent by making remote objects look like local objects. The only difference from a user of a remote service perspective would be how the object itself is obtained. RMI is based on three abstraction layers. Stub / Skeleton layer; Remote Reference layer; Transport layer
Stub ? A stub is a representation (proxy) of the remote object at client. It resides in the client system; it acts as a gateway for the client program. Skeleton ? This is the object which resides on the server side. stub communicates with this skeleton to pass request to the remote object. RRL(Remote Reference Layer) ? It is the
The Stub/Skeleton Layer. The stub/skeleton layer is the interface between the application layer and the rest of the RMI system. A stub for a remote object is the client-side proxy for the remote object. Such a stub implements all the interfaces that are supported by the remote object implementation.
