Java and RMI

The aim of the job is to develop an information service for road assistance, that will inform to a client that needs help how long he has to wait and what emergency unit will take care of him. The architecture of the information service allows to connect with many road assistance units that are in different locations, choosing the one nearest to the client to take care of him. The way the architecture works should be: 1)The client has an emergency, he contacts with a central server and sends his personal info and his geographical position (simulate de info) 2)Once the server receives the info, it interrogates the road assistance units reporting the event. 3)Each road assistance unit answers with info about the distance on the event. 4)The central server choose, depending on the answers received, what unit will take care of the event, answering then the client request. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform The communication between the client and the central server will be developed in Java, using the RMI services with sockets implementation. The communication between the server and the road assistance units has to be done using multicast services. Everything else is up to the developer.
