Re: jFreeChart, Cewolf tag library, OS/400, Tomcat

[Patrick L Archibald <Patrick.Archibald@xxxxxxxxxxxxx>]

Colin,

I added java.awt.headless=true and everything is working now.  I thought 
I tried that before I installed PASE but maybe I didn't. Anyone care to 
try setting  java.awt.headless=true and try running a Java application 
on a system without PASE installed to see if you get any messages 
relating to PASE?


Thanx, PLA
