It was copied when I pointed my jpackage input directory to my old application’s Java directory but I am guessing it is no longer in class path. I suppose just jar’ing the resources into a file in the Java directory would be an easy enough fix, although to me maybe slightly less convenient.

There may be no need. At this point I would guess probably not.

It was within the application image though…

Normal jars go to <app>/Contents/Java

AppBundler included the directory.

which was also automatically added to classpath. You could add property files, html editor kit css files, scripts or whatever, and classloader load them. Since I was a little used to digging into the app’s I found it convenient to use. Again, remembering that for a lot of purposes an OS X application bundle can be treated a lot like a plain old directory itself.
