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

Patrick,

You've probably already spotted that your properties arent getting picked
up. 
Im sure there is a way to override the properties without setting them at
the system level. 

I presume you have to set these before you start the JVM, so I would think
you could pass these as arguments to the JVM.

Cheers
Colin.W

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


Hi

Has anyone seen the stack trace below before? Do you know what it means? 
I've developed some Tomcat 4.1.24 jsp pages that display charts using 
jFreeChart and Cewolf tag library. It all works on my PC but fails on 
the AS/400 with the message below. I've tried setting 
os400.awt.native=true or java.awt.headless=true in my 
/qibm/userdata/java400/SystemDefault.properties file but it causes other 
problems. I'm at V5R2 jdk 1.4.


Thanx, PLA
