The important part of the error message is here:

Error: Unable to initialize main class org.jupyterkernel.kernel.Session Caused by: java.lang.NoClassDefFoundError: org/zeromq/ZMQException

When the kernel is launched it is not finding the zeromq class. You need to add the jeromq-0.3.6 jar file to your classpath, as well as the commons-cli-1.2.jar and json.jar. I don't know why the documentation does not note this.
