The Web Start version if fully functional with the exception
of the Jython actor, which uses some strange caching mechanism.

I've seen this problem with Windows Cygwin jar before, where it is not
entirely compatible with the Sun jar.
Try putting the JDK bin in your path before /usr/bin.
I'll see about making a test for this in configure.
If you really want to use /usr/bin/jar, try editing
$PTII/mk/ptcommon.mk and change
(cd $(PTJAR_TMPDIR); "$(JAR)" -cvf tmp.jar .; "$(JAR)" -i tmp.jar)
to
(cd $(PTJAR_TMPDIR); "$(JAR)" -cvf tmp.jar .)
in three places.
The -i option is used to generate an index for the jar file which
make applications and applets start faster.

Seems like your Java installation is broken and not finding
any the runtime jar file that contains java.lang.Object.
I don't have a good solution for this, I don't have a Linux machine in
front of me.
Under Solaris, Object.class can be found in:
[EMAIL PROTECTED] 9% jar -tvf /opt/local/j2sdk1.4.1_02/jre/lib/rt.jar | grep
java/lang/Object.class

However, adding rt.jar to the classpath should not be necessary.
The way that I would proceed is to poke around on the
Sun tutorial and make sure that your JVM works
http://java.sun.com/docs/books/tutorial/getStarted/cupojava/index.htmld
Also, you should be able to start vergil by hand by including
lib/diva.jar
Something like the following should work:
java -classpath ${PTII}:${PTII}/lib/diva.jar ptolemy.vergil.VergilApplication

Yep, the classpath can be a bear.

The Java Web Start Application Manager is a standalone application
that lists the Web Start applications that are available.
http://java.sun.com/j2se/1.4.2/docs/guide/jws/Readme.html#install
Under Windows, there is a standalone Java Web Start Application under
Start -> All Programs -> Java Web Start
Under Solaris (for me_, there is standalone Java Web Start Application zip
file installer at
/opt/local/j2sdk1.4.1_02/jre/javaws-1_2_0_02-solaris-sparc-i.zip
