[kepler-users] Setting parameters for command line execution

[GARY WERNSING]

I am trying to pass a parameter to a workflow via the command line. Chapter two of the user manual suggests it is straight forward and that adding '-x 4 -y "foo"' to the command line would set both x and y. I am starting to think there is something unspoken about actually using this technique.

I have a workflow that executes properly when I run it from the Kepler GUI but fails when run from the command line. My command line is:

/Applications/Kepler-2.4/Kepler.app/Contents/Resources/Java/kepler.sh -runkar -ScriptLocation "/Users/wernsing/rest.py" /Users/wernsing/KeplerData/workflows/MyWorkflows/RESTviaPython.kar

At some point later I get

...
    [null] Command failed.
    [null] ptolemy.actor.TypeConflictException: Types resolved to unacceptable type . .RESTviaPython due to the following objects:
    [null]   (variable .RESTviaPython.ScriptLocation: unknown)
...

My workflow has three Port Parameters one of which is named "ScriptLocation". When I run the workflow from the Kepler GUI I get the expected result (a file appears on my desktop) so I have some confidence that the workflow is correct. I am baffled as to how to get the command line invocation to set the Port Parameters.

Any advice and/or magic incantations would be greatly appreciated.
