The problem is that you haven't set your classpath appropriately. I suspect you need to put quotes around

example;lib/kvclient-1.2.123.jar

C:\oracle\kv-ee-1.2.123\kv-1.2.123>java -cp "example;lib/kvclient-1.2.123.jar" hello.HelloBigDataWorld

or

C:\oracle\kv-ee-1.2.123\kv-1.2.123>set CLASSPATH="example;lib/kvclient-1.2.123.jar"
C:\oracle\kv-ee-1.2.123\kv-1.2.123>java hello.HelloBigDataWorld

Note that in general we do not support running KV on windows. You may run into additional anomalies on that platform.

On Linux don't use ; to separate classpath elements. Use :.

Note that you're having a simple Java classpath problem, not a NoSQL Database problem.
