Re: Print JPEG HeadlessException - Please Help
Looks like this is set for sure. I even tried running with Java 1.5. I think I might be beyond help, time to look for a new trade.

RE: Print JPEG HeadlessException - Please Help
Just in case it means something, I ran into this problem when java.awt.headless was specified as true on the startup configuration for the OAS platform. Since we were running on a Windows PC we were successfully able to run Batik (and thereby FOP) by just changing java.awt.headless=false (or removing all together). From my investigation at the time (albeit on FOP 0.20.5 and Batik 1.5beta4), the only way to successfully make it work was to run in a non-headless environment. In short, I did not find a way for FOP (and more specifically Batik) to work in a headless environment, regardless of what you set your properties to. -Original Message- From: Surj [mailto:[EMAIL PROTECTED] Sent: Friday, July 18, 2008 4:50 AM To: fop-dev@xmlgraphics.apache.org Subject: Re: Print JPEG HeadlessException - Please Help Looks like this is set for sure.
