Using the three-tier software architecture presented in this chapter, design and implement a client-server suite for the following protocol (it is not a well-known service): Each client sends to the server a name. The server accumulates the names received from successive clients (by appending each, with a linefeed (" '), to a static string). Upon receiving a name, the server sends the names that it has collected to the client. The figure below illustrates the sequence diagram of a session of the protocol. a. Is this server a stateful server? If so, what kind of state information (global or session) does it maintain? b. Use any one of the following suites to implement this protocol: (1) connectionless server and client, (2) connection-oriented, iterative server and client. (hand in both source JAVA code and sample execution observation) Using the three-tier software architecture presented in this chapter, design and implement a client-server suite for the following protocol (it is not a well-known service): Each client sends to the server a name.
