How to initiate chatting between two clients and two clients only, using applets and servlets?

hop of those help? You need to store all connected users in a Map in the application scope using ServletContext#setAttribute(). The String denotes the unique user identifier (chat nickname?). You need to store the specific chat User as well in the session scope using HttpSession#setAttribute(). You also need to store the other user in individual chats in a Map in the session scope of the users in question. You can obtain the attribute by the getAttribute() method.
This way you know which users are all available and which user is in the current session and with which users it is individually chatting.

will be helpful for those in need A short answer is: it is not possible.
One of the main problems is that router do not know where to redirect the request from the server (or other client). Just a case : You have a router which has multiple devices(computer, cell phone...) behind it. It gets a request and do not know, who wants to get the request.

around this issue After a few brain meltdowns , I have decided that putting a server socket on the client side to listen for updates from the server is the best way. I fixed a few things : * The server should start a new thread to handle every accepted connection, instead of processing each one in-line in the accept thread. * I tried to get the first update via the server socket instead of the login initialization. now, after getting the 1st update while logging in, I added a Server Socket on the client side so it will keep listening for further updates from server.

will help you You should consider using WebSockets. If you are in a Java EE context (and you say you are) then the web sockets API is available to you, if it's Java EE 7 or more.
With web sockets, your (Java EE) server side can push the game data to each of your (HTML5) clients.

this one helps. I have a requirement to show Gross profit and GP% for the top 5 clients. I have created the Gross profit bar chart for top 5 clients and its correct as expected. I have concatenated the client and branch columns in table Revenue and used that to get top 5 clients. , I fixed my issue by creating the following measure.
code :
% GP per Client = DIVIDE (
SUM ( revenue[GrossProfit] ),
CALCULATE ( SUM ( revenue[GrossProfit]), ALL (revenue[Client And Branch])
