So what is the best practice for developer to frequently execute
predefined jelly script?

In my project, process is defined in xml file, which will not be
changed logically, which could be very complicated. Logically volatile
stuff is variables (like current user name and form data). It's easier
for me to model process definition with tag/scripts and put variables
into JellyContext. Otherwise, I can not figure out any solution else.

What is your suggestions? Thanks
