Thanks. I see how it works now -- very neat.

Ok, I've got ant working (thanks to the supplied build.xml on the
rosjava wiki page you linked to, although there was a small error in
the XML file which I've corrected on the wiki) but I can't seem to
find any way to run the compiled classes using rosrun. Is this
possible, or do we have to manually execute nodes using java
-classpath <path> package.class ?
Thanks again,
Mark
