Java Remote Method Invocation Specification Free download
Locate remote objects Applications can use one of two mechanisms to obtain references to remote objects. An application can register its remote objects with RMI’ssimple naming facility, thermiregistry, or the application can pass and return remote object references as part of its normal operation. • Communicate with remote objects Details of communication between remote objects are handled by RMI; to the programmer, remote communication looks like a standard method invocation. • Load class bytecodes for objects that are passed as parameters or return values Because RMIallowsacaller to pass objects to remote objects, RMI provides the necessary mechanisms for loading an object’scodeaswellas transmitting its data. The illustration below depicts an RMI distributed application that uses the registry to obtain references to a remote object. The server calls the registry to associate a name with a remote object.

Implementing Asynchronous Remote Method Invocation in Java Free download

Introduction Communication protocols in distributed object systems often do not explore the full range of possible optimisations due to the desire for simplicity and the maintenance of a consistent interface and underlying protocol. It is possible to create specialised implementationsofthese communications protocols, but generally these implementations are not completely compliant with the standard implementation. This leads to a reluctance on the partofthe software developers to explore optimised or extended protocols. Java ’sRemoteMethod Invocation (RMI) mechanism [5,29]is an example ofa standardised communications protocol that provides a limited setofoptimisations. RMI provides a remote communications mechanism between Java clients and remote objects. Java clients obtain references to these remote objects through a third party registry service. These references allow transparent access to the remote object’s methods by mirroring the remote interface. All method invocation is performed in asynchronous manner unless explicitly subverted by the client and server implementations. Java RMIimplementations are currently very slow on LAN networks, which is a problem for real- time and parallel distributed applications. Java RMI has been designed for Internet applications for which higher latencies are not as important as for real-time and parallel systems. Several parallel implementations ofJava over RMI have isolated someofthe problems with Java RMI, such asserialisation protocols and restrictive interfaces [13,17].
