You cannot include jars in a jar. The classloaders will not find classes inside of multiple jars.
To do this, you'll need to write ( or find) a custom classloader or better add classes to your JAR File's Classpath according to

Also make sure that your manifest file ends with an empty line, otherwise the last line in the manifest file will not be parsed correctly.

See this page, which says:

"Warning: The text file from which you are creating the manifest must end with a new line or carriage return. The last line will not be parsed properly if it does not end with a new line or carriage return."
