Robocode Editor/Compiler troubles?
Hmm - it says: "java.lang.ClassNotFoundException: dz.MostlyHarmlessNano_2.1.dz.MostlyHarmlessNano", and all the other class names seem similarly warped. I think the class it should be looking for is just "dz.MostlyHarmlessNano". Could you check the filename of MostlyHarmlessNano's JAR? Is it dz.MostlyHarmlessNano_2.1.jar, or something else? I'm wondering if the RoboRumble client did something weird in downloading to the wrong filenames and it's throwing off the class names that Robocode expects to find.
