You need to enable xServer for java2d to be running. try the same piece of application on Tomcat. If u get DISPLAY 0.0 bla bla error then it must be something wrong with the java2d. Carefully read the FAQ's and in that there is one question which talks about when the same webapplication is shifted from windows to Linux it doesnt work. Just see that. They have given two links to answer that question.

You need to enable xServer for ur jfreecharts to work as they intern use java2D. i hope this will help
