It is to develop a chat tool that should consist of a server and a client component. The server should allow clients to  create chat-rooms  list all existing rooms  join existing chat-rooms  send messages to chat-rooms  leave a chat-room Once created, chat-rooms store all data (messages sent to the room) for as long as they exist. If a chat-room has not been used for more than 7 days, it should be destroyed. The server should support up to 10 concurrent clients. The client should provide an interface that enables a user to  create a room,  list the existing rooms,  join one or more existing chat-rooms  send messages to chat-rooms  leave one or more rooms If the user connects to a chat-room all previously sent messages of that room should be displayed. New messages sent by the user or other connected users should be shown to the user. It is required to : - Implement the web services as REST web services (the application should be a command line application, everything should be run from terminal no GUI).

I am assuming that you need the client just for testing since it does not need a GUI. I will provide alternative request based testing method for the API. What is the purpose of the chat server that it does not need performance metrics?
