[kepler-users] Understanding Kepler at Java Level

[ben leinfelder]

Josep -
I believe you can accomplish your first goal by invoking the "command  
line" as an external process from  your Java code. The workflow  
execution web service that Jing Tao helped develop essentially does  
exactly what you are aiming to do: load a KAR, execute the workflow in  
it, get the result KAR when execution finishes.
For your second request, you'd probably have to dig much deeper into  
the Kepler/ptolemy code to add a parameter to the MOML after it was  
loaded. Perhaps the folks more familiar with ptolemy can point you in  
a good direction.
