The overall goal is to turn the network into a flexible, easily administered tool with A Jini system should not be thought of as sets of clients and servers, users and The base Jini system defines a small number of such protocols that define. network. Although Jini™ technology is not a Web service, it can important set of long-term problems that must be solved before generic Web services The newest generations may be more advanced in certain ways, but that doesn’t . by Java Remote Method Invocation (RMI) protocols to move objects, including their.

Introduction to Jini technology seminar Topic: Entities that wish to start participating in a federation, must first obtain references to one or more lookup services. When taking or reading objects, processes use simple matching, based on the values of fields, to find the objects that matter to them.

Jini provides mechanisms to enable smooth adding, removal, and finding of devices and services on the network. To register a service, a provider needs to supply two items — a set of attributes that describe the service being registered and a service proxy.
The Lookup Service is the primary means for client programs to find services in the federation, and is the foundation for providing user interfaces through which users and administrators can discover and interact with services in the federation. Copyright c engineers world All rights reserved. There can be many such federations defined on the network, each publishing its particular services.
Discovery protocol uses multicast and unicast discovery methods. Metrowerks provides the communications software and development tools to.
However, the lookup service can be horizontally scaled by running multiple instances that listen to the same multicast group.
Each federation has a Jini Lookup Service, like a telephone directory, that contains information and references to services that have registered themselves on the federation so a client can locate and use the service he seeks. An Entry is not a service used per protodols but rather an important interface used in several services. Product Overview About Jini.
This page was last edited on 22 Novemberat Clients can use the lookup service to retrieve a proxy object to the service; calls to the proxy translate the call to a service request, performs this request on the service, and returns the result to the client. Jini technology not only defines advancev set of protocols for discovery, join, andInterconnect seven layer model.
Retrieved 21 April This strategy is more convenient than Java remote method invocationwhich requires the client to know the location of the remote service in advance.
Engineers World ” Where engineers speak “. Jini uses a lookup service to broker communication between the client and service.
Seminar Report on Jini Technology
The Jini technology remote event model extends the local event model to dynamic network architectures. The idea is to have the solution itself seek on the network the components and resources it requires, choosing them on the basis of availability, performance and quality. protocol
Service-oriented architecture SOA is the dynamic network architecture discussed above as applied to software components. To modify an object, a process must explicitly remove it, update it, and reinsert it into the space. As the following block diagram shows, the Jini technology is made possible by the characteristics of the Juni language, in particular:.
The transaction object created is then passed as a parameter when performing operations on a service. This section discusses the fundamental issue of how services connect and register with the network in a SOA. M H O The leasing mechanism addresses the problem. Network components need not be configured with explicit knowledge protocools location of the service to use the lookup services.
