In ftp://ftp.santafe.edu/pub/swarm/2.0.1-fixes/diffs the patch
java-xprint.diff adds SwarmEnvironment methods for running the Swarm describe: 
methods.  The Windows stuff in the directory above is also updated.

Below is an example of how to make use of these methods.  In Objective
C Swarm `xprint' is a macro that calls the describe method on the
object, and `xfprint' calls the describe methods for each member
in a collection, where a collection is the argument to xfprint. 

Note that if you are using SUN JDK with Windows, you'll need to run
your model under the debugger so that the output stream gets set up
right.  Like this:

$ JAVASWARMGDB=gdb javaswarm TestZonePrint
(gdb) run

import swarm.Globals;
import swarm.defobj.ZoneImpl;
import swarm.defobj.Zone;
import swarm.objectbase.SwarmObjectImpl;

public class TestZonePrint {
  static public void main (String args []) {
    Globals.env.initSwarm ("TestZonePrint", "0.0", "address@hidden", args);

    Zone newZone = new ZoneImpl (Globals.env.globalZone);

    new SwarmObjectImpl (newZone);
  
    Globals.env.xprint (newZone);
    Globals.env.xfprint (newZone.getPopulation ());
  }
}
