Dear readers,

My first blogpost because blogs are known for problems and such.

I have started programming in Java years ago, but now i have to revisit the Runtime after a long periode of C-sharp and C++ programming.

I have to build a Server who can handle multiple clients, and the client. I tried to build a single-connection-server/client, but both applications wait or sleep for the other side to react.

I hope anyone can help me with this. I have googled for tuts, but i can't seem to get the picture.

tl:dr gimme the source server/client-model java-code or help to create it myself.

depends on how scalable it must be:

also simple client/server examples should be everywhere around the net.

Thank you all.. but i need to write the code for a server/client model in java programming. Not a server for files or mysql/php.

Have you tried the tutorials from sun? It's what I used to try it out, and it worked without a problem.

imo mina is overkill. Just go with a simple socket and serversocket implementation.

1 - Create a ServerSocket and bind it to a port number.
2 - Poll on the port. Polling is fine for single threads but if you need this to scale for a lot of connections, you will need java.nio and use selectors along with ServerSocketChannel.
3 - The client will probably use the Socket class and connect to your server. Use it's InputStream and OutputStream to receive and send messages.
