I was actually wrong here, I think. I should probably check closer, but I now think that clojure only mangles its own package names when necessary. I don't think it ever mangles doing pure interop. > exactly!!! when I ask from clojure (:import [encog-java.customGA aClass]) > clojure should convert the hyphen to match the actual package found in the > declaration of class files.

I don't get it!!! I actually just tried this (I don't recommend this approach though), and it worked for me, maybe you missed a step. I think you'll have best luck if you make your directory structure match the package name. --Aaron -- You received this message because you are subscribed to the Google Groups "Clojure" group.
