Get java.lang.NoClassDefFoundError after adding library

I have downloaded java code and try to launch it on examples that are provided there. In particular I run java edu.toronto.cs.propagation.ic.ICEstimate -m 50 -d 1e-8 -s data/memeS.sn -i data/memeS.out -o data/memeS.probs from the main directory. However, I get the following message:

I have specified CLASSPATH and PATH as following:

export PATH="/home/sergey/miniconda/bin:$PATH" export CLASSPATH="/home/sergey/workspace/Spine/javalib/:$CLASSPATH" export CLASSPATH="/home/sergey/workspace/Spine/spine.0.1.jar:$CLASSPATH"

and I have jsap library in my javalib folder.

What can be the problem? How can I run the code?
