Re: JESS: Retrieving slot and multislot values

I don't know the context (sorry) in which you're doing this, so you'll  
have to make up your own mind. Read this for some info:

You can always use the global context for a Rete object by calling  
Rete.getGlobalContext() . If you absolutely, positively know that a  
value contains no variables, and no function calls that produce a  
variable or reference a Rete object, then you can get away with  
passing "null" -- but getGlobalContext() is safer, of course.
