Problem with deployment

I am using JBoss IDE 1.6 (built on Eclipse) and developing a web app that utilize JFreeChart (through Cewolf tags in JSPs). It works fine when I ran it on my local machine.

However, when I deploy it onto the production server (JBoss 4.0.1), the chart is not drawn and an exception is thrown (see below).

Anyone else having this problem? Thanks.

Just got my problem fixed, it's because JFreeChart calls Java2D, which requires a display environment, which is not available on the Linux server. So, I changed the batch file to add -Djava.awt.headless=true to tell JVM to use a headless display. See below link for details:
