[kepler-dev] External Execution Actor: Pls suggest

[Christopher Brooks]

Hi Subhav,
Try using the full path to xyz.app as an argument to External Execution
Actor. Perhaps there is an issue with the path.

It could be that Kepler is being invoked with a path that is
different than the path you are getting with cmd.

I'm fairly certain External Execution Actor uses ptolemy.actor.lib.Exec.
See the documentation at
http://ptolemy.eecs.berkeley.edu/~ptII/ptolemyII/ptIIlatest/ptII/doc/codeDoc/ptolemy/actor/lib/Exec.html
You can set the environment parameter to include a particular path.

The Exec actor is tricky to use because of path issues.  The Exec actor
uses the Java Runtime.exec() method, so looking at docs for Runtime exec
might be of use.
