[kepler-dev] Using the latest revision of Ptolemy gives problems

Hi Faraaz,
I'm not seeing those errors building Ptolemy II within Eclipse.
 From the error.txt file, it looks like you are building Kepler
using Eclipse.

The CommPortIdentifier errors and other errors occur because
I upgraded from Sun's JavaComm, which is basically no longer
supported to RXTX, which can be found at

You could either install RXTX or use Eclipse to exclude

When building Ptolemy under Eclipse, configure searches for
the RXTX jar file and if it is not found, then
ptolemy/actor/lib/io/comm is excluded.  Also $PTII/.classpath.default
excludes that directory by default.  However, building Kepler
under Eclipse does not use configure so it does not search
for RXTX.  Hence the reason the Ptolemy Eclipse build would
work and the Kepler Eclipse build would not.

About _createSizeAttribute, this is probably a problem with
a Kepler copy of a Ptolemy file.

I'll see if I can build Kepler under Eclipse sometime soon, but
it will be a few days.
