I am using all libraries correctly: If you were, you wouldn't have that exception, would you? The jar file doesn't have the correct Class-Path manifest entry, or the required jar files are not where they should be. What's the content of the manifest? Where are the libraries located? – JB Nizet

Do you want to execute demoBioMini.jar? You missed out the classpath, "./java/BioMiniSDK.jar"

Try this. 

$ java -classpath "./java/BioMiniSDK.jar;./demoBioMini.jar" demoBioMini

Or, you can run demoBioMini_Java.bat in the same directory.

$ demoBioMini_Java.bat
