I use jfreechart throughout my application. All the components are packaged regularly in the .jar file. (the whole package is an .ear). More experimenting shows it is not jfreechart only (if I comment out the @Name("chartGraphPage") then it dies on the next component). It exceptions on any of my classes that include anything from the war/WEB-INF/lib. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4091161#...
