Bean Scripting Framework Question

Hello,

Can someone who knows about Jakarta BSF project help me on this :

I am trying to run a jython script from java. Ive created a BSFManager and i can execute the script with its "exec" method. However i have modified the script to accept arguments (sys.argv[1]). How can i pass arguments from within BSFManager and how can i capture its output? I think there is a method "apply" which does this but i don't understand how to use it.

I want to pass to my script a String argument and get back a String result

Thanks
