    Hi is there a quite on how to setup ZeroMQ to run on a Servlet container?
    Kevin Sapper
    @sappo
    @incube8r I don't get your question? What is your use case?

    Hello,
    I want to try jeromq. I would like to know when is there going to be a stable release?

    @incube8r
    @sappo atm I have this Spring (Java) Websocket server that is used to accept video and audio chunks for live streaming, I am wondering if I can user ZeroMQ with Java and replace Websocket for live streaming

    @sappo
    @incube8r technically I don't see why it shouldn't work. But I have never done it before ...

    hi there
    are there some up-to-date java examples somewhere?
    the docs of jeromq say that the guide is outdated
    Adam Arold
    @adam-arold
    for example i have no idea how to receive multiplart messages
    from a subscriber
    is this project abandoned?
    Kevin Sapper
    @sappo
    @adam-arold the docs are wrong. The examples in the zguide are up to date.
    To learn about PUB/SUB have a look at https://zguide.zeromq.org/docs/chapter5/
    Kevin Sapper
    @sappo
    Here's an example to receive a multipart message from a socket
     // Receive message from ZMQSocket "input" socket object and iterate over frames
 ZMsg receivedMessage = ZMsg.recvMsg(input);
 for (ZFrame f : receivedMessage) {
     // Do something with frame f (of type ZFrame)
 }
    Another example could be
    ZFrame receivedFrame; 
do {
    receviedFrame = ZFrame.recvFrame(input);
    // Do something with frame
} while (receivedFrame.hasMore());
    And no the project is not abandoned

    @adam-arold
    where ist his documented?
    can you point me to it?
    I read this chapter, but it doesn't talk about ZMsg
    although i didn't read it till the end
    thanks anyway, this is what I was looking for
    do you have plans for fixing the API issues of JeroMQ?
    Adam Arold
    @adam-arold
    I mean the scoping problem of Zmq.Socket
    even if I have a subscriber i can still call send and all the other functions on it
    i don't really know what's supposed to happen if I try to recv from a publisher
    stuff like that
    Kevin Sapper
    @sappo
    The socket API is intentionally designed like to to work with arbitrary socket types. The behavior of each socket is described in a rfc. E.g..
    the rfc for pubsub https://rfc.zeromq.org/spec/29/
    Adam Arold
    @adam-arold
    it is just not idiomatic in Java
    and on the JVM in general
    this is C style coding
    Kevin Sapper
    @sappo
    Feel invited to propose an Java idiomatic API wrapper around ZMQ.Socket. JeroMQ has no paid maintainers so any contributions are welcome 😊
    Kevin Sapper
    @sappo
    Btw there's also the ZSocket class
    Adam Arold
    @adam-arold
    do you have anyting planned?
    Kevin Sapper
    @sappo
    I don't, but I'm open to suggestions

    Hi Guys, I am evealuating jeromq for a low latency project. But i could not find a way to stop gc calls.Even the simplest client server applications require gc cycles after a while because of socket.recv calls. Is there any way to reuse same buffer for each recv call? I try to pass a static buffer to method but it does not seem working.

    Hi Team,

    Can someone help me to escape special characters ( like \n ) when passing messages through ZMQ
    As I can see that those characters are getting parsed when passed through ZMQ.

    Thanks

    @ashmeet-kandhari zeromq doesn't touch your data. Where does your error occur
    ASHMEET KANDHARI
    @ashmeet-kandhari
    @sappo We are using pushpin and using zeromq transport (which pushpin has support out of the box) to publish messages to pushpin
