Hi Wade,
I don't think I have a WinXP installation at hand, but I was able to run
the MatlabExpression demo under Windows Server 2003 with a 32-bit JVM
from a clean install of Kepler-2.3. Windows Server 2003 is fairly
similar to XP.
To determine the bit width of your JVM, start up Kepler, go to Tools ->
check settings and look at the value of
sun.arch.data.model = 32
When I start a dos shell (Start->Run->cmd), I can start matlab from the
command line, which works for you.
My path looks like:
C:\Documents and Settings\cxh.NEWTON>set PATH

Note that the Matlab bin and bin\win32 directories are in my path.
One thing is that the error message for the first time a matlab model is
run is usually more informative that the stack trace you submitted.
After the Matlab interface has failed, then for subsequent runs, the
stack trace tends to just say that the Matlab class cannot be found.
Another thing to do is to take a look at the mailing list, various
people have had various issues with Matlab. Try searching with:
site:lists.nceas.ucsb.edu kepler-users Matlab
I don't have Matlab installed on my Windows Server 2008 R2 64-bit
machine, but I can work on that. This machine is fairly similar to
Windows 7 64-bit. I would not be able to get a license until Monday.
Hope this helps, let us know how it goes.

Hi folks,
I'm trying to test using Kepler 2.3 to execute matlab-based workflows,
since we use matlab extensively for environmental data management at a
US LTER site. I started with the demo "MatlabExpression.xml", but I
haven't been able to get it to run. I confirmed that the relevant
matlab directories are in the system path and I can invoke matlab from
a command prompt, so that's not the issue. I can also run Python and
R-based demos and do other simple things, so there doesn't appear to
be anything wrong with my base Kepler installation. I also tried using
various matlab versions (R13, R2010a, R2011b, adjusting the path to
matlab\bin and matlab\bin\win32 accordingly), disabling security
software and running from an admin user account in desperation, but
those steps didn't help.
Any advice would be appreciated. I've only tried running this in WinXP
SP3 32bit, but I could also try Win7 64bit tomorrow on another
workstation. Below is the stack trace of the error I get when running
the workflow.
Thanks.

stack trace:
ptolemy.kernel.util.IllegalActionException: There was a problem
invoking the Ptolemy II Matlab interface.
The interface has been tested under Linux, Mac OS X, and Windows.
The interface requires that Matlab be installed on the local machine
and that the ptmatlab shared library available.
* Under Linux, you must have the LD_LIBRARY_PATH environment variable
set to include the directories that contain libmx.so and libptmatlab.so.
* Under Mac OS X, you must have the DYLD_LIBRARY_PATH environment
variable set to include the directories that contain libmx.dylib and
libptmatlab.jnilib.
* Under Windows, you must have your PATH set to include the Matlab
bin/win32 or equivalent directory so that libmex.dll is found and the
directory that contains libptmatlab.dll. In addition, if you are
running under Windows from the Cygwin bash prompt, then you must start
Vergil with the -jni argument: $PTII/bin/vergil -jni. For details, see
$PTII/jni/package.html.
