怎样解决 no jzmq in java.library.path

由 元气小坏坏 提交于 2020-10-28 10:24:33
确保zmq的各种library有安装正确。检查方法：查看/usr/local/lib， 看里面有没有libjzmq.a, libjzmq.dylib, libzmq.a, libjzmq.dylib 2.正确的安装方法是：（1）安装libzmq-master （2）安装zeromq-3.2.4，注意版本号最好选这个。试过最新版本号会报错 （3）安装jzmq-master java binding 直接搜这些关键词都能找到对应地github网页或者官网，然后按步骤输指令即可 。 3.看看问题是不是出在java.library.path，打开 ~/.bash_profile, 增加 export LD_LIBRARY_PATH=/usr/local/lib. 或者直接在命令行里提供路径，比如： javac -classpath /usr/local/share/java/zmq.jar HelloWorldClient.java java -classpath .:/usr/local/share/java/zmq.jar -Djava.library.path=/usr/local/lib HelloWorldClient 在按照 ZeroMq官方 提供的方法 $ ./autogen.sh$ ./configure$ make$ make install

Why one might need JeroMQ if it can use JZMQ?

由 别等时光非礼了梦想. 提交于 2020-07-18 11:50:28
问题 Simple question. Why "porting" zmq on java and call it JeroMQ is good idea? 回答1: JeroMQ is an official project of the ZeroMQ community; it's a full port of the C++ libzmq library, supporting version 3.2. Advantages: Pure Java, so no need to link in C/C++ via JNI. This is extremely helpful on devices where native libraries are difficult or impossible. 100% compatible with the JZMQ API (the two projects agreed on a single API so you can import one or the other transparently). 100% compatible

Get TCP address information in ZeroMQ

由 浪子不回头ぞ 提交于 2020-07-18 10:03:27
问题 I want to connect clients to a server using ZeroMQ (java bindings, jzmq), but I need the TCP information badly, for example the TCP/IP address of a client request! The problem is, for being able to announce a service in the network I need to grab the TCP address of a request to be able to redirect clients to that service. The broker is a central "service registry" in that case. However, having ZeroMQ services on both sides, I do not see an option to retrieve that information. What I do now,

问题 I want to discover all Android devices IP and Port in same wifi network using ZeroMQ? My app basically connect all device in same wifi network (no internet needed) and message to each other. Once ip and port I know I am send message successfully but how to know all device internet Protocol (ip) Using ZeroMQ? 回答1: Principle Part A) Every IEEE 802.x CSMA/CD network "collision domain" ( wifi AP/SSID is such one ) has to be managed so as to work well.

No messages match using SUB in Java with ZeroMQ

由 こ雲淡風輕ζ 提交于 2019-12-23 06:05:46
问题 I'm trying to use Java client with ZeroMQ. When subscribing to any prefix, the Java client matches no messages, although a similar Python client matches messages as expected. The Python server context = zmq.Context() socket = context.socket(zmq.PUB) socket.bind("tcp://*:5556") for i in range(100): r = "XXX " + i socket.send_string(r) time.sleep(random.randint(0,10)) The Python client working fine context = zmq.Context() socket = context.socket(zmq.SUB) socket.connect("tcp://localhost:5556")

问题 I am trying to implement using XPUB and XSUB as provided in this below figure. I have gone through their examples provided but could not get one for XPUB and XSUB in Java. Here they have given an example in C which is little complex as I am new to ZeroMQ. I am trying to use it in android using jni wrapped version. Please help me to find an example, how to implement this Pub-Sub Network with a Proxy in ZeroMQ using java. Currently I am referring http://zguide.zeromq.org/page:all I have tried
