Java应用程序中的zeroMQ UnsatisfiedLinkError

Question

i have written a application that communicates via zeroMQ with another application. On my development machine running Ubuntu 13 is all well and working.

I do have zeroMQ 4.4.0 installed, also the jzmq java binding did compile without errors.

But on our testing/production server i get this. The application starts up and from requestInit() it tries to request it's configuration from the main configuration manager over zeroMQ.

bs@server-01:~/$ java -Djava.library.path=/usr/local/lib -jar /home/bs/opengraphchild/jar/opengraph.jar 5000 opengraph1
Params = 5000
Params = opengraph1
Starting Test service ...
Running
TestService.requestInit()
Exception in thread "main" java.lang.UnsatisfiedLinkError: org.zeromq.ZMQ$Socket.nativeInit()V

I could not find anything relevant to my issue so i'm asking you guys. Please help :( [don't know if you need to see sourcecode, since it's working on my local machine, but i can add it]

Answer 1

This is what I got to make it work on Windows, OS X and Ubuntu:

http://sourceforge.net/p/jalgo/code-0/HEAD/tree/trunk/src/org/aso/algo/messaging/bus/zmq/ZMQLoader.java#l17

The bus package also contains pub/sub establishment so feel free to refer to it.
