Thanks for the feedback.
There is a bug with Java3D 1.3 and Ptolemy II 2.0.1.
Below is what I did to replicate it:
1. On a Window XP laptop, uninstalled all previous versions of
the Java SDK, JRE and Java 3d.
2. Rebooted
3. Installed Java 1.4.1_01 SDK
4. Installed Java 3d 1.3 Direct X. Note that Java 3d 1.3.1-beta
is also available. I did not try it this time, but I believe that
Java 3d 1.3.1-beta should work if Java 3d 1.3 works.
5. Installed Ptolemy II 2.0.1 by using the Windows installer.
6. Ran the GR demos, the demos run, but nothing but a black window is
displayed.
I believe I fixed this last October with the following change
to ptII/ptolemy/domains/gr/lib/ViewScreen.java
***************
*** 265,274 ****
while (branches.hasMoreElements()) {
BranchGroup branchGroup = (BranchGroup) branches.nextElement();
if (branchGroup.getCapability(BranchGroup.ALLOW_DETACH)) {
! if (!(branchGroup instanceof
! com.sun.j3d.utils.universe.ViewingPlatform)) {
! simpleUniverse.getLocale().removeBranchGraph(branchGroup);
! }
}
}

while (branches.hasMoreElements()) {
BranchGroup branchGroup = (BranchGroup) branches.nextElement();
if (branchGroup.getCapability(BranchGroup.ALLOW_DETACH)) {
! simpleUniverse.getLocale().removeBranchGraph(branchGroup);
}
}
7. I added the java bin directory to my path
8. Downloaded the source version of Ptolemy II 2.0.1 and recompiled
9. Verified that the bug still occurred.
BTW - In the console, I saw the following message:
Fail to create hardware D3D Device, switch to use reference rasterizer. -
D3DERR_OUTOFVIDEOMEMORY
10. Made the above patch, recompiled ViewScreen.java
11. Ran the GR demos and they worked.
> Worth a note on the web site.
I created a patched version of ViewScreen.java and also a
new version of experimentalDomains.jar for the Windows Installer that
include this fix.
See the limitations page of
http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII2.0/
That page also has a note about the Jini issue.
I sprinkled some links about Java 3d around the Ptolemy II 2.0 pages
as well.

With regard to Soot, our development tree works with the new version
of Soot that works with Java 1.4.x.
Patching the release would be tricky, so this change will have to wait
for the next release of Ptolemy II in May.
For a little more info about Soot and running Ptolemy II under Java
1.4, see my post from January 11 at

Thanks, this is a useful exercise, since it points out issues that me
might need to address in the devel tree for the next release and
it gives me a chance to update the limitations page for the current
release.
BTW - I recompiled Ptolemy II 2.0.1 from source using Java 1.4.1_01
and Java 3d 1.3 and not get any errors about Jini because Jini was not
found when configure was run.
The configure output looked like:
checking for jini directory... configure: warning: 'Failed to find
$PTII/vendors/sun/jini/jini1_0_1/lib/jini-core.jar
Perhaps Jini is not installed?
You need not download Jini unless you plan on use Jini and
JavaSpaces
Jini can be downloaded from http://java.sun.com/jini' and placed
in $PTII/vendors/sun/jini/jini1_0_1'
I agree that we should update or remove the Jini actors for the next
release.
Thanks again for reporting the GR bug, and let us know if you find
other issues.
