You need to replace all of these with the appropriate (load-lib
vtkConeSource "libraryName"). The vtkConeSource there is fairly
arbitrary, it's just any class that was loaded by the correct
ClassLoader.

Where did this "vtkCommonJava" come from? It must be "loadLibrary0".
You're trying to call a method that doesn't exist.
To be clear, the top of your file should look like:
(defn wall-hack-method
"Calls a private or protected method.
params is a vector of class which correspond to the arguments to the method
obj is nil for static methods, the instance object otherwise
the method name is given as a symbol or a keyword (something Named)"
[class-name method-name params obj & args]
(-> class-name (.getDeclaredMethod (name method-name) (into-array
Class params))
(doto (.setAccessible true))
(.invoke obj (into-array Object args))))
(defn load-lib [class lib]
"Loads a native library in the same classLoader as class was
loaded in, lib is a string with the OS-appropriate name of the
library. For instance, to load libvtk.so on Linux, lib should be
\"vtk\""
(wall-hack-method java.lang.Runtime "loadLibrary0" [Class String]
(Runtime/getRuntime) class lib))
(load-lib vtkConeSource "vtkCommonJava")
(load-lib vtkConeSource "vtkFilteringJava")
(load-lib vtkConeSource "vtkIOJava")
(load-lib vtkConeSource "vtkImagingJava")
(load-lib vtkConeSource "vtkGraphicsJava")
(load-lib vtkConeSource "vtkRenderingJava")
