KY> I would like to add the "super" class's variables and messeges to

KY> Will you please tell me how to do with java code?

You may need to build the snapshot sources to get this working...

Below is Java code that demonstrates one approach.  
(Step toward the base of the class hierarchy, checking each ProbeMap.)

import swarm.Globals;
import swarm.objectbase.VarProbe;
import swarm.objectbase.EmptyProbeMapImpl;
import swarm.objectbase.ProbeMap;
import swarm.defobj.Zone;
import swarm.simtoolsgui.GUISwarm;
import swarm.simtoolsgui.GUISwarmImpl;

class BaseClass {
  public double val1;
  public String val2;
}

class SubClass extends BaseClass {
  public int val3;

  SubClass (double val1, String val2, int val3) {
    super ();
    
    this.val1 = val1;
    this.val2 = val2;
    this.val3 = val3;
  }
}

class SuperProbeMap extends EmptyProbeMapImpl {
  SuperProbeMap (Zone aZone, Class aClass) {
    super (aZone, aClass);
  }

  VarProbe getProbeForVariable (String name, Class clas) {
    VarProbe vp =
      Globals.env.probeLibrary.getProbeForVariable$inClass (name, clas);

    if (vp == null)
      {
        clas = clas.getSuperclass ();
        if (clas != null)
          vp = getProbeForVariable (name, clas);
      }
    return vp;
  }

  void addProbeForVariable (String name) {
    addProbe (getProbeForVariable (name, getProbedClass ()));
  }
}

public class SuperProbeMapTest extends GUISwarmImpl {
  SuperProbeMapTest (Zone aZone) {
    super (aZone);
  }

  public Object buildObjects () {
    super.buildObjects ();

    SubClass subClass = new SubClass (1.0, "Hello World", 2);
    SuperProbeMap probeMap = new SuperProbeMap (getZone (),
                                                subClass.getClass ());

    probeMap.addProbeForVariable ("val1");
    // probeMap.addProbeForVariable ("val2");
    probeMap.addProbeForVariable ("val3");

    Globals.env.probeLibrary.setProbeMap$For ((Object) probeMap,
                                              subClass.getClass ());

    Globals.env.createProbeDisplay (subClass);
    return this;
  }

  public Object buildActions () {
    super.buildActions ();
    return this;
  }

  public static void main(String[] args) {
    Globals.env.initSwarm ("SuperProbeMap", "0.0","mgd@swarm.org", args);
    
    GUISwarm guiSwarm = new SuperProbeMapTest (Globals.env.globalZone);

    guiSwarm.buildObjects ();
    guiSwarm.buildActions ();
    guiSwarm.activateIn (null);
    guiSwarm.go ();
  }
}
