Design and implement a simple Distributed Auctioning System using Java RMI.

The system will consist of an auctioning Server and two Clients. One of the clients named as Seller should be able to create a new auction, preferably with an Auction ID, for an item to be sold quoting a starting price and the reserve price (i.e., the minimum price of the item expected). The reserve price is kept secret. The auction is time bounded, which means that, the Seller should be able to close the auction after a specified time or when the deadline is reached. When an auction is closed, the Seller should either display the details of the winner or should inform that the reserve price is not attained. The second client is called Buyer. This client is meant for placing a bid against the items under auction. The Buyer should be able to fetch the list of active auctions and bid for a selected item using the details of the buyer like Name and mobile number. The Server should deal with requests from both Seller and Buyer maintaining the appropriate details of items, auctions, sellers and buyers.

a) Design of the basic architecture for the whole application

b) Design of proper RMI interfaces and implementation

c) Implementing Client and Server programs with exception handling
