I got the properties to take. It just caused other problems. I'm 
thinking I need to install: iSeries Tools for Developers PRPQ (5799PTL) 
before I can turn the properties for awt on.   All the jFreeChart 
software is doing is building a PNG graphic that is displayed via the 
Cewolf jsp tags. It is a shame the AS/400 is requiring all this extra 
attention.

Thanx, PLA
