You use -classpath OR -jar, not both.

-jar
     Execute a program encapsulated in a JAR file. The first argument is 
the name of a JAR file instead of a startup class name. In order for 
this option to work, the manifest of the JAR file must contain a line of 
the form Main-Class: classname. Here, classname identifies the class 
having the public static void main(String[] args) method that serves as 
your application's starting point. See the Jar tool reference page and 
the Jar trail of the Java Tutorial for information about working with 
Jar files and Jar-file manifests.

     When you use this option, the JAR file is the source of all user 
classes, and other user class path settings are ignored.
