Apologies for my spleen filled outburst above. Frustration got the better of me.
I don't have write access to the wiki so I can't edit it myself, although I've already sent Casey a message to ask him to add the relevant details in.
the step by step guide should read something like:
1) Locate the jogl-natives-windows-amd64.jar and gluegen-rt-natives-windows-amd64.jar in your "processing\libraries\opengl\library" folder.
2) either use the "jar -xvf" command to unpack these Jar files (or just rename the .jar extension to .zip and use your favourite unzip tool)
these Java Archives (JAR) contain (among others) the following files:
gluegen-rt.dll
jogl.dll
jogl_awt.dll
jogl_cg.dll
3) overwrite your original files of the same name with these you've just unpacked.
job done.
As Koogy has shown us, the standard processing installation contains all the files you need to do this, you don't need to go and download them from jMonkeyEngine.
