[OSM-dev] I've committed a whole new set of mappaint icons - how do I compile the jar file?!?

First of all, thanks a lot, that was exactly what I needed :-)))

After tweaking with the paths (setting JAVA_HOME to the SDK bin dir and 
adding ant to the PATH) all is running smooth now. As my first steps 
with eclipse failed, I'm running ant from the command line, and 
compiling mappaint works smoothly now. As you might have seen, I'm 
already working on it, I've committed my first bugfix and I'm working 
now on more flexibility for the elemstyles.xml file (different rules for 
different zoom levels, rules for subkeys, ...) - it's currently just too 
simple for some interesting things ;-)
