[kepler-users] Understanding Kepler at Java Level

[Josep Morer Muñoz]

Yes, I am executing using command line inside Java but I want independency
between my application and the operating system where Kepler is running.

Thanks Ben, sounds interesting. Where can I find this workflow execution web
service for looking into it? I assume that it allow to set a parameter value
different than workflow default ones (as command line execution).
