I am trying to get the security list response from the Fix Server using QuickFix4J, but I am getting following error :
<20230201-05:21:05, FIX.4.4:targetId->senderId, error> (Reject sent for message 2: Tag not defined for this message type, field=110)
Here's my request :
private void getSecurityList(SessionID sessionID){
String id = UUID.randomUUID().toString();
System.out.println("Sending security list request : >>>>>>>>>>> ");
SecurityListRequest request = new SecurityListRequest();
request.getHeader().setField(new MsgType(MsgType.SECURITY_LIST_REQUEST));
request.getHeader().setField(new SenderCompID(senderId));
request.getHeader().setField(new TargetCompID(targetCompanyId));
request.set(new SecurityReqID(id));
request.set(new SecurityListRequestType(SecurityListRequestType.ALL_SECURITIES));
try {
Session.sendToTarget(request);
} catch (SessionNotFound e) {
throw new RuntimeException(e);
}
}
here's my FIX config :

Here's how I handle the response :

public void handleFromApp(FromApp fromApp) throws FieldNotFound {
System.out.println("From App : ");
Message message = (Message) fromApp.getMessage();
System.out.println("From App Message Type : " + message.getHeader().getString(MsgType.FIELD));
// SessionID sessionID = fromApp.getSessionId();
if (message instanceof MarketDataSnapshotFullRefresh){

orderBookService.getOrderBookFromFix(marketData);
}
if (message instanceof ExecutionReport){
ExecutionReport executionReport = (ExecutionReport) message;
newOrderService.handleOrderStatus(executionReport);
}
try {
String msgType = message.getHeader().getString(MsgType.FIELD);
System.out.println("Message Type : " + msgType);
if (MsgType.SECURITY_LIST.equals(msgType)){
System.out.println("Received security list response >>>> mapping now >>>>>>>> ");
securityListResponseMapper(message);
}
} catch (FieldNotFound e) {
throw new RuntimeException(e);

I have a simple netty connection pool and a simple HTTP endpoint to use that pool to send TCP messages to ServerSocket. The relevant code looks like this, the client (NettyConnectionPoolClientApplication) is:
#SpringBootApplication
#RestController
public class NettyConnectionPoolClientApplication {
private SimpleChannelPool simpleChannelPool;
public static void main(String[] args) {
SpringApplication.run(NettyConnectionPoolClientApplication.class, args);
}
#PostConstruct
public void setup() throws Exception {
EventLoopGroup group = new NioEventLoopGroup();
Bootstrap bootstrap = new Bootstrap();
bootstrap.group(group);
bootstrap.channel(NioSocketChannel.class);
bootstrap.option(ChannelOption.SO_KEEPALIVE, true);
bootstrap.remoteAddress(new InetSocketAddress("localhost", 9000));
bootstrap.handler(new ChannelInitializer<SocketChannel>() {
protected void initChannel(SocketChannel socketChannel) throws Exception {
ChannelPipeline pipeline = socketChannel.pipeline();
pipeline.addLast(new DelimiterBasedFrameDecoder(8192, Delimiters.lineDelimiter()));
pipeline.addLast(new StringDecoder());
pipeline.addLast(new StringEncoder());
pipeline.addLast(new DummyClientHandler());
}
});
simpleChannelPool = new SimpleChannelPool(bootstrap, new DummyChannelPoolHandler());
}
#RequestMapping("/test/{msg}")
public void test(#PathVariable String msg) throws Exception {
Future<Channel> future = simpleChannelPool.acquire();
future.addListener((FutureListener<Channel>) f -> {
if (f.isSuccess()) {
System.out.println("Connected");
Channel ch = f.getNow();
ch.writeAndFlush(msg + System.lineSeparator());
// Release back to pool
simpleChannelPool.release(ch);
} else {
System.out.println("not successful");
}
});
}
}
and the Server (ServerSocketRunner)
public class ServerSocketRunner {
public static void main(String[] args) throws Exception {
ServerSocket serverSocket = new ServerSocket(9000);
while (true) {
Socket socket = serverSocket.accept();
new Thread(() -> {
System.out.println("New client connected");
try (PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
BufferedReader in = new BufferedReader(
new InputStreamReader(socket.getInputStream()));) {
String inputLine, outputLine;
out.println("Hello client!");
do {
inputLine = in.readLine();
System.out.println("Received: " + inputLine);
} while (!"bye".equals(inputLine));
System.out.println("Closing connection...");
socket.close();
} catch (Exception e) {
e.printStackTrace();
}
}).start();
}
}
}
DummyChannelPoolHandler and DummyClientHandler just print out events that happen, so they are not relevant. When the server and the client are started and I send a test message to test endpoint, I can see the server prints "New client connected" but the message sent by client is not printed. None of the consecutive messages sent by client are printed by the server.
If I try telnet, everything works fine, the server prints out messages. Also it works fine with regular netty client with same bootstrap config and without connection pool (SimpleNettyClientApplication).
Can anyone see what is wrong with my connection pool, I'm out of ideas
Netty versioin: 4.1.39.Final
All the code is available here.
UPDATE
Following Norman Maurer advice. I added
ChannelFuture channelFuture = ch
.writeAndFlush(msg + System.lineSeparator());
channelFuture.addListener(writeFuture -> {
System.out
.println("isSuccess(): " + channelFuture.isSuccess() + " : " + channelFuture.cause());
});
This prints out
isSuccess: false : java.lang.UnsupportedOperationException: unsupported message type: String (expected: ByteBuf, FileRegion)
To fix it, I just converted String into ByteBuf
ch.writeAndFlush(Unpooled.wrappedBuffer((msg + System.lineSeparator()).getBytes()));
You should check what the status of the ChannelFuture is that is returned by writeAndFlush(...). I suspect it is failed.

}
Please find my observations below:
In the event logs I am seeing as Created session: and the message which I am trying to send. Also I could see that the sender sequence number is getting incremented in the logs.
Messages.log and header.logs are blank and body.log has the message which i am trying to send.
Also onCreate and ToApp are being called when I try to run the code.
I want to know whether i have sent the message successfully ?
Also boolean sent = Session.sendToTarget(msg, sessionId); is returning false.
I don't see ToAdmin and FromAdmin being executed in my code. Also Do I need to write the acceptor code as well for the same, or just the initiator code will be fine. The DataDictionary which i am using has all the fields set, but I am not sure whether its being used by QuickFixJ when i try to execute the code.
Please advise whats going wrong in this?
OK your settings file looks ok and you're saying it works, but I don't think you need GATEWAY and TRANSPORT headings
As for your code, all you need to do to start with is setup the default QuickFIX Application, FileStoreFactory, LogFactory, MessageFactory and Initiator which you have done.
The default QuickFIX automatically logs on to the Target in your settings file, and if the logon is accepted then it begins to heartbeat. From your comments it sounds like this is happening.
So what's going wrong is your sendLogonRequest is not necessary. Also, if you do send "extra" logons then the target FIX engine will probably reject or ignore them. The reject message would be seen in the logs or file store.
So then you have the QuickFIX API with which to start with you can simply output messages to your own log.
Something like this
public void fromApp(Message msg, SessionID s) throws UnsupportedMessageType, FieldNotFound, IncorrectTagValue
{
log.debug(String.valueOf(LocalTime.now()) + " INITIATOR: FromApp " + msg.toString());
}
public void toApp(Message msg, SessionID s)
{
log.info(String.valueOf(LocalTime.now()) + " INITIATOR: ToApp " + msg.toString());
}
public void fromAdmin(Message msg, SessionID s) throws FieldNotFound, IncorrectTagValue
{
Log.trace("INITIATOR: FromAdmin " + msg.getClass() + " " + msg.toString());
}
public void onCreate(SessionID s)
{
log.info("INITIATOR: OnCreate " + s.toString());
}
public void onLogout(SessionID s)
{
log.error("INITIATOR: OnLogout " + s.toString());
}
public void onLogon(SessionID s)
{
log.info("INITIATOR: OnLogon " + s.toString());
}
public void toAdmin(Message msg, SessionID s)
{
log.trace("INITIATOR: ToAdmin " + msg.getClass() + " " + msg.toString());
}
Then when you want to send a message, try something like this:
QuoteReqID id = new QuoteReqID("1234");
// Create Quote Request message
QuoteRequest qr = new QuoteRequest(id);
// Setup outgoing group and specify an index for each group tag
NoRelatedSym g = new NoRelatedSym();
String instrument = m.getString("EUR/USD");
Symbol symbol = new Symbol(instrument);
g.setField(1, symbol);
QuoteRequestType qt = new QuoteRequestType(102);
g.setField(2, qt);
OrderQty qty = new OrderQty("1000000");
g.setField(3, qty);
SettlType sType = new SettlType("B");
g.setField(4, sType);
SettlDate sDate = new SettlDate("20170315");
g.setField(5, sDate);
Account account = new Account("357647");
g.setField(6, account);
// add group to request
qr.addGroup(g);
Session s = Session.lookupSession(i.getSessions().get(0));
s.send(qr);
I am using Java Jetty client written [websocket-client 9.3.8.RC0]. Websocket server is little wierd in our case.
It accepting request in format.
wss://192.168.122.1:8443/status?-xsrf-=tokenValue
Token Value is received in first Login POST request in which i get Token Value & Cookie header. Cookie is added as a header whereas token is given as a param.
Now question is : -
When i run below code it just call awaitclose() function in starting. But there is not other function called i.e. Onconnected or even Onclose.
Any help would be appreciated to debug it further, to see any logs or environment issue to see why Socket is not connected.
Trying to figure out following points to debug.
1. To check if client certificates are causing issue.
Tried with my python code wspy.py it work seemlessly fine.
Code is
public final class websocketxxx {

MyWebSocket socket = new MyWebSocket();
try {
client.start();
ClientUpgradeRequest request = new ClientUpgradeRequest();
// Add the authentication and protocol to the request header
// Crate wss URI from host and resource
resource = resource + xsrfVal;
URI destinationUri = new URI("wss://" + host + resource); // set URI
request.setHeader("cookie",cookieVal);
request.setHeader("Sec-WebSocket-Protocol", "ao-json");
//System.out.println("Request Headers print : " request.getHeaders())
System.out.println("Connecting to : " + destinationUri);
client.connect(socket, destinationUri, request);
socket.awaitClose(5000, TimeUnit.SECONDS);
} catch (Throwable t) {
t.printStackTrace();
} finally {
try {
client.stop();
} catch (Exception e) {

The implementation is mostly correct.
Setting raw Cookie and Sec-WebSocket-* headers is forbidden, you have to use the API.
Cookie handling from:
ClientUpgradeRequest request = new ClientUpgradeRequest();
request.setHeader("cookie",cookieVal);
To ClientUpgradeRequest.setCookies() :
ClientUpgradeRequest request = new ClientUpgradeRequest();
List<HttpCookie> cookies = new ArrayList<>();
cookies.add(new HttpCookie(...));
request.setCookies(cookies);
Note: if you are using the java CookieStore, then you can pass the CookieStore instance to the client as well, using the setCookiesFrom(CookieStore) method.
Sub Protocol Selection from:
ClientUpgradeRequest request = new ClientUpgradeRequest();
request.setHeader("Sec-WebSocket-Protocol", "ao-json");
To ClientUpgradeRequest.setSubProtocols():
ClientUpgradeRequest request = new ClientUpgradeRequest();
request.setSubProtocols("ao-json");
I have tried to establish chat connection between two users using xmpp and OpenFire. But i am not able to send and receive message. I have pasted my code below for reference. Any help will be very helpful.
I established a connection with Smack by
XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
config.setUsernameAndPassword("admin", "admin");
config.setServiceName("172.21.4.199");
config.setHost("172.21.4.199");
config.setPort(5222);
config.setDebuggerEnabled(true);
config.setConnectTimeout(50000);
XMPPTCPConnection connection = new XMPPTCPConnection(config.build());
XMPPTCPConnection.setUseStreamManagementResumptiodDefault(true);
XMPPTCPConnection.setUseStreamManagementDefault(true);
try {
connection.setPacketReplyTimeout(50000);
connection.connect();
Log.d(TAG, "SetupDefaults -- Connected");
} catch (Exception e) {
e.printStackTrace();
Log.d(TAG, "SetupDefaults -- Connection failed exc: "+e);
}
and its gets succesfully connected. And i try to send a chat by using
ChatManager chatManager = ChatManager.getInstanceFor(connection);
Chat chat = chatManager.createChat("user2#server.local", new ChatMessageListener() {
#Override
public void processMessage(Chat chat, Message message) {
System.out.println("processMessage -- Sent message: " + message);
}
});
try {
chat.sendMessage("Hai.. Lets we chat!");
}catch (Exception e){
Log.d(TAG, "sendChat Exc: "+e.toString());
}
But i couldn't find that processMessage gets triggered. Because that S.O.P doesn't gets triggered. But i gets
SMACK: SENT (0): Hai.. Lets we chat!
SMACK: RECV (0): Hai.. Lets we chat!
in my console while sending a chat.
Simillarly i use,
PacketListener packetListener = new PacketListener() {
#Override
public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
Message message = (Message)packet;
String from = message.getFrom();
String body = message.getBody();
System.out.println("Message from: " + from + " " + body);
}
};
connection.addPacketListener(packetListener, filter);
to receive the chat. But processPacket also doesn't gets triggered.
PacketListner it's something much more general to handle stanzas, it's not what you really need. You just need a ChatMessageListner
ChatManager chatManager;
chatManager = ChatManager.getInstanceFor(connection);
chatManager.addChatListener(
**new ChatManagerListener() {
#Override
public void chatCreated(Chat chat, boolean createdLocally)
{
if (!createdLocally)
{
chat.addMessageListener(new IncomingMessageListener());;
}
}
})**;
Basic implementation:
class IncomingMessageListener implements ChatMessageListener {
#Override
public void processMessage(Chat arg0, Message message) {
String from = message.getFrom();
String body = message.getBody();
if (body != null)
{
System.out.println(String.format("============ Received message '%1$s' from %2$s\n============", body, from));
guiUpdate.displayMessage(body); /* custom method */
}
else
{
System.out.println("SYSTEM: ping");
}
}
I want to send a message to my computer from my phone using TCP..My computer is the server and my phone is the client. I am able to send a message from my phone to my computer but in the output, I get null characters ..
I paste my codes below;;
Client ::
public void startApp() {
try {
// establish a socket connection with remote server
streamConnection =
(StreamConnection) Connector.open(connectString);
// create DataOuputStream on top of the socket connection
outputStream = streamConnection.openOutputStream();
dataOutputStream = new DataOutputStream(outputStream);
// send the HTTP request
dataOutputStream.writeChars("Hello");
dataOutputStream.flush();
// create DataInputStream on top of the socket connection
inputStream = streamConnection.openInputStream();
dataInputStream = new DataInputStream(inputStream);
// retrieve the contents of the requested page from Web server
String test="";
int inputChar;
System.out.println("Entering read...........");
while ( (inputChar = dataInputStream.read()) != -1) {
// test=test+((char)inputShar);
results.append((char) inputChar);
}
System.out.println("Leaving read...........");
// display the page contents on the phone screen
//System.out.println(" Result are "+results.toString());
System.out.println(" ");
resultField = new StringItem(null, results.toString());
System.out.println("Client says "+resultField);
resultScreen.append(resultField);
myDisplay.setCurrent(resultScreen);
} catch (IOException e) {
System.err.println("Exception caught:" + e);
} finally {
// free up I/O streams and close the socket connection
try {
if (dataInputStream != null)
dataInputStream.close();
} catch (Exception ignored) {}
try {
if (dataOutputStream != null)
dataOutputStream.close();
} catch (Exception ignored) {}
try {
if (outputStream != null)
outputStream.close();
} catch (Exception ignored) {}
try {
if (inputStream != null)
inputStream.close();
} catch (Exception ignored) {}
try {
if (streamConnection != null)
streamConnection.close();
} catch (Exception ignored) {}
}
}
My server :
public class Main {
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
try{
ServerSocket sck=new ServerSocket(880);
Socket client=sck.accept();
InputStream inp= client.getInputStream();
int i;
OutputStream out=client.getOutputStream();
out.write("Testing ".getBytes());
System.out.println("Server has responded ");
String str="";
while((i=inp.read())!=-1){
str=str+((char) i);
System.out.println("USer says "+ str);
}
}
catch(Exception e){
System.out.println("Error "+e);
}
}
}
My output for the server ;;
Server has responded
USer says null H
User says null H null
User says null H null e
etc etc
I am not supposed to get this null character,why I am getting it??
Another thing, my server is writing to the stream but the client is not able to receive that,why is that?Do I need to use a separate thread for that?
Thanks in adv
I would guess that isn't your real code, and that your real code initialized str to null.
