Everything is working. What follows is a description of what I had to do. I didn't need to build in a special way to get command line functionality, despite what http://dev.processing.org/reference/everything/javadoc/processing/app/Commander.html said. I also found that that document said that the preferences file is optional, but in practice it will abort if preferences.txt is not in your path. To get around this, I had ant start the jvm in processing's directory. Chances are, the build.xml will work for you, as long as you change the value of the "processingDir" property to the location of the processing directory on your system. All arguments to the Commander class are supplied in args.properties all on one line; they are imported into build.xml under the "args" property, and ran with java. I chose to keep args to Commander class in this file, because I plan to programmatically change the contents of this file.
HOPE THIS HELPS!!
