CoralFIX comes with a ready-to-use server implementation that you can fire and start accepting connections from your FIX clients. It will handle all the FIX session level details like logon, heartbeats, sequence reset, resend request, etc. To implement a simple server for your tests all you have to do is:
import com.coralblocks.coralfix.FixMessage;
import com.coralblocks.coralreactor.client.Client;
import com.coralblocks.coralreactor.nio.NioReactor;
import com.coralblocks.coralreactor.util.Configuration;
import com.coralblocks.coralreactor.util.MapConfiguration;
public class SimpleFixApplicationServer extends FixApplicationServer {
public SimpleFixApplicationServer(NioReactor nio, int port, Configuration config) {
super(nio, port, config);
}
@Override
protected void handleFixApplicationMessage(Client client, FixMessage fixMsg, boolean possDupe) {
// do whatever you want to do with the application message received from this client...
}
public static void main(String[] args) {
NioReactor nio = NioReactor.create();
MapConfiguration config = new MapConfiguration();
// print all messages received and sent to STDOUT for debugging purposes
// (default is false)
config.add("debugMessages", "true");
// accept as the client inbound sequence whatever
// sequence I receive in the first message coming from the client
// (default is false)
config.add("acceptInboundSeqFromClient", "false");
Server server = new SimpleFixApplicationServer(nio, 45451, config);
server.open();
nio.start();
}
}
