Hi Andrew,
I'm not totally sure what you are getting at here.
If you look at
$PTII/ptolemy/domains/sdf/demo/Butterfly/Butterfly.java,
then you will find that it defines a class that extends
TypedCompositeActor.
To run the class with a run control panel, run:
java -classpath $PTII ptolemy.actor.gui.CompositeActorApplication -class
ptolemy.domains.sdf.demo.Butterfly.Butterfly
$PTII/ptolemy/actor/gui/CompositeActorApplication.java says:
This application creates one or more Ptolemy II models given a
classname on the command line, and then executes those models, each in
its own thread. Each specified class should be derived from
CompositeActor, and should have a constructor that takes a single
argument, an instance of Workspace. If the model does not contain
a manager, then one will be created for it. The model is displayed using
an instance of ModelFrame, which provides controls for executing
the model and setting its top-level and director parameters.
$PTII/ptolemy/actor/gui/CompositeActorSimpleApplication.java
will work with non-graphical models
If you run this command:
java -classpath $PTII ptolemy.actor.gui.CompositeActorApplication -class
ptolemy.actor.gui.test.TestModel
Then you will run a really simple model that does not print anything,
but it does run.
However, this model below will print to stdout:

Perhaps you are not instantiating a director?
Now, there could be an issue with a particular domain.
It took a quick look at creating headless java based models for the
wireless domain by using Copernicus shallow codegen and it looks like
Copernicus shallow codegen does not work with AtomicWirelessChannel.
These demos
1. domains/wireless/test/auto/range.xml
2. domains/wireless/test/auto/delay.xml
3. domains/wireless/test/auto/erasure.xml
4. domains/wireless/test/auto/properties.xml
5. domains/wireless/test/auto/properties5.xml
6. domains/wireless/test/auto/powerLoss.xml
7. domains/wireless/test/auto/powerLoss2.xml
Fail with this message:
Exception occurred: class ptolemy.kernel.util.IllegalActionException(Cannot
determine location for port port.)
ptolemy.kernel.util.IllegalActionException: Cannot determine location for port
port.
at
ptolemy.domains.wireless.kernel.AtomicWirelessChannel._locationOf(AtomicWirelessChannel.java:677)
I suspect that the problem here is that we are filtering out the
Locatable class somewhere.
This might be affecting you?

--------
In our effort to build a headless Ptolemy model (Giri posted about it earli
er this week), we find that most of our actors do not become "full citizens"
of the new model. As a result, nothing happens when we execute the model.
We tried to model our code on MoMLSimpleApplication and the entity-creation
code in MoML parser:
// The top-level TypedCompositeActor is named "world"
// mote extends TypedCompositeActor
NamedObj moteClone = (NamedObj) mote.clone(world.workspace());
world.workspace().add(moteClone);
moteClone.setName("MoteActor " + i);
((ComponentEntity)moteClone).setContainer(world);
// This differs on purpose from the "_location" parameter
Parameter position = (Parameter) moteClone.getAttribute("position");
// ...
Actors added this way make it into the manager's contained entity list, but
not into the entity cache. When we call execute(), the method returns almo
st immediately, and none of the actors we tried to add using the above metho
d are initialized ...
Thanks for your guidance,
Andy Z.
