Handling 2 Clients

Question

hello everybody,
i have a simple question.
i have an application where a clients sends a string and server accepts it,finds the string length and return it to client.
as far as this is concerned , all is fine.
but i want to send this string length to second client on the same server.
i am using RMI.
server returns the length but it is by default sent to the client invoking that function.i want it to be sent to second client.
can anybody tell me how to go about it.
i know it may be simple but i am new to distributed technology.
thanks in advance,
sachin

Hi,
How do you get the reference of second client?
If it is a very simple application like two clients call two methods on
the same remote object, then you can make the second thread(client) wait until first one sends that string. And as soon as the server computes string length, then notify the waiting the thread and make it return with the length.
But, a better way of doing this thing is through RMI callbacks. Your second client registers with the server (through your own register method) passing its own reference. And whenever the server wants to send the length, then call back the second client with the reference that it stored at time of registration.
