The default Java class loader cannot find an embedded jar inside a jar file. You will need to set your Java program to use a class loader which can deal with embedded jar files. As fas as I know, I have not seen one in any opensource libraries so you may need to write one yourself.

Alternatively, you can extract all the jar files and combine the the content into a single jar file.

Clean way to combine multiple jars? Preferably using Ant
