Hi, The latest Kepler version 1.0.0beta3 is not working on two different linux systems tested. Is it known to work on other linux systems?
I downloaded the zipped archive of kepler20070102 and installed the files on my linux machine: $ cat /etc/redhat-release Scientific Linux Fermi LTS release 4.1 (Wilson) $ cat /proc/version Linux version 2.6.9-22.0.2.EL $ java -version java version "1.4.2_12" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_12-b03) Java HotSpot(TM) Client VM (build 1.4.2_12-b03, mixed mode) Kepler fails with these errors: $ sh ./kepler.sh KAR Library directories: [./kar/actors, ./kar/directors] The class name you entered was not found in the classpath.

Perhaps there is a classpath problem of the karlib needs to be flushed? <... deleted lines ...> ptolemy.kernel.util.IllegalActionException: Error building tree model: Error building tree model: Could not clone actor 'File Reader' from the 'util.FileReader' class, the actor null, meaning it was not found?
