[kepler-users] Python execution within the Kepler Python actor...

[J. Marc Edwards]

Christopher:

Ok... Thanks for clarifying the status of Jython in Kepler. Having said this, I would like to advance the objective of upgrading Kepler to use the latest version of Jython, namely version 2.5.2. Can you work with me on this task?

The task is primarily focused upon upgrading Ptolemy. Perhaps we can also gain some assistance from someone on that team as well.

What do you think of this idea?

Regards, Marc
