I know my question would be a bit strange. Of course the book is not about the JFreeChart.
But I can't wait to ask the author here about the wierd thing of JFreeChart... I'm wondering if he had to face that problem with JFreeChart when he tried to play around with it...

Jeff and David,
I had pretty much experience with JFreeChart before... I tried to develop Charting application in Windows and run it on Tomcat... It's perfectly good... But when I tried to deploy the WAR into the JRun server on HP-UX... It says that XWindows did not start the Graphics server or sthing like that... I tried to ask about it in the dicussion forum own by JFreeChart group... But they always responded me that the problem is of my Unix servers, not of JFreeChart... I also saw many other people asking about it in many threads... But the response from JFreeChart group had been the same...

My question is that "Did you face such problem with JFreeChart when you wrote this book?"... Of course the book is not about the JFreeChart... Well, most of the Portal Server will be deployed on Unix... So I'm just wondering if this problem is discussed in the book... Thanks...

Hi,

I think this is actually a generic Java problem, not a specific JFreeChart problem. You need to look into running the Java AWT in a headless environment for HP/UX.

Check http://java.sun.com/j2se/1.4.2/docs/guide/awt/AWTChanges.html#headless for more details.

Hope this helps,
Jeff
