ClassNotFoundException and NoClassDefFoundError while using Jaunt Library?

Question

I am working on a web scraper using the Jaunt library. I am currently getting the runtime error while on the linux terminal:

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: com/jaunt/JauntException

while running:

java -cp .:.classes/jaunt1.3.3.jar class_name

The directory of my .jar file looks like this:

leo@blah:~/workspace/Java/classes$ ls -al
total 164
drwxrwxr-x 2 leo leo   4096 Sep 13 17:25 .
drwxrwxr-x 4 leo leo   4096 Sep 15 10:59 ..
-rw-rw-r-- 1 leo leo 157786 Sep 11 19:40 jaunt1.3.3.jar

and my classpath looks like this:

leo@blah:~/workspace/Java/classes$ echo $CLASSPATH
~/workspace/Java/classes:home/leo/workspace/Java/classes/:home/leo/workspace/Java/classes/jaunt1.3.3.jar

Can someone help me out? Thanks!
