Java Path zeromq设置

Question

I am using MAC OSX

I already follow the instruction on 0mq official site to install

when i compile it , i dont get any error.

But when i run the following command

java -classpath /Users/john/jzmq/ -cp $(lein classpath) storm.starter.WordCountTopology

I got the following error.

java.lang.UnsatisfiedLinkError: no jzmq in java.library.path

My setting $ echo $JAVA_HOME /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home

I also have zmq.jar under
/usr/local/lib and

/usr/local/share/java

I read through all the google search I can found. Still no crew why my one is not working

Answer 1

In addition to setting the JAR classpath, you need to specify where the jzmq .so library files reside. Did you build zmq, libzmq, and jzmq exactly as described in the directions? If so, you should see the .so library files in /usr/local/lib and zmq.jar in /usr/local/share/java , confirm that, then logout/login based on this , then try this:

java -Djava.library.path=/usr/local/lib -cp  "/usr/local/share/java/zmq.jar:/Users/john/jzmq/<your jar here>" storm.starteer.WordCountTopology

Hope it helps
