FIX protocol using java

Question

I have developed a utility in Java using the Financial Information eXchange(FIX) protocol to pull data from an input stream. However, I currently have not found any test servers online to which I can connect to that implement the FIX protocol. Could someone please let me know how I can achieve this?

Solution 1

http://www.quickfixj.org/ have an open source fix engine. It comes with an example that has a simple server. You might want to use their library for the client too rather than rebuilding a FIX engine from scratch...

Solution 2

You can use CoralFIX to quickly fire up a test server. It takes care of all the session level FIX messages, such as Logon, ResendRequest, SequenceReset, Heartbeat so you are ready to start exchanging messages with your client. Below a simple example:

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();
    }
}
