When you use java -jar all classes must be in the JAR or pointed to by the Class-Path attribute of the MANIFEST.MF file. Environment variables and -cp arguments are ignored (http://docs.oracle.com/javase/7/docs/technotes/tools/windows/java.html).

Here is how to set up the manifest.mf file

But usually the "can not find main class" usually means exactly that it can not find the main class. Otherwise you would get classloader errors or other errors. Make a simple hello-world java class without external libraries and see if you can get it running from a jar-file, when that works go on to add external libraries and see what happens.
