mmmm... this is where a new org.jfree.chart.axis.NumberAxis instance is
created. 

Three reasons I can think of for the breakage:

1 - If you are running your server in a non-graphical environment (i.e.
without a windowing environment like X), you need to start the JVM (for
Tomcat) with the -Djava.awt.headless=true property. In non-graphical
environments without this property set, JFreeChart cannot init (as it
expects to find a graphical environment). It works fine with the
property set, though.

2 - Perhaps your WEB-INF/lib/jfreechart-0.9.21.jar file is corrupt or
unreadable? It should contain the org.jfree.chart.axis.NumberAxis
classfile.

3 - (improbable) Is it possible that you have another (older) jfreechart
jar in your classpath (and that it is freaking out the 0.9.21 one)?
