Ptolemy II 3.0.2 Notes for Mac OS X

Mac OS X Java 1.4 Instructions

Ptolemy II 3.0.2 requires Java 1.4 because it uses the java.net.URI class which is not present in Java 1.3.
Mac OS X 10.2 is required to run Java 1.4. http://developer.apple.com/java/faq/index.html#gen_1 says:

Q: What version of Java is included on Mac OS X?

A: Apple is now shipping a J2SE 1.4.1 implementation for Mac OS X 10.2 Jaguar, available via the Software Update mechanism. It is based on the J2SE 1.4.1_01 JDK with the HotSpot Client VM.

Mac OS X Web Start Problems

Under Mac OS 10.2 with Java 1.4, the Web Start binary downloads and starts up, but there might be a delay while the rest of the modules are pulled over the network.

Mac OS X UI bugs

Drag and Drop does not work
Dragging an actor from the actor library pane on the left results in 
java.lang.ClassCastException

The following Sun Java Topic might be of use http://forum.java.sun.com/thread.jsp?thread=184916&forum=5&message=654598

Making ptolemy/vergil/toolbox/PtolemyTransferable.java implement Serializable might help. Editing how the DataFlavor is created in PtolemyTransferable might also help: 

   public static final DataFlavor namedObjFlavor =
    new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType +
            ";class=ptolemy.kernel.util.NamedObj", "Named Object");
The above change was added between Ptolemy II 3.0-beta and Ptolemy II 3.0.2.
There are problems with the right mouse button
Usually click and hold or Control-click simulates the right button, but not under HyVisual
In Ptolemy II 3.0.2, we modified
ptolemy/vergil/actor/ActorEditorGraphController.java to use Command-Click to create new relations and drag new edges
