RE: [jCharts-users] NoClassDefFoundError

[Jaap S. <co...@ja...>]

Both system have jsdk1.4.2 installed (RedHat does not ship any java I
think because it is closed source). I try to keep the systems as similar
as possible.

I also thought it should be a classpath issue (usually it is) but even
the /catalina-home/work/... directories are the same on both systems.
(The 'work' folder contains all the complied code used by Tomcat to run
the web application). 

I use png -> see the result:
http://test.jaap.nl/charts/what.png
http://jaap.nl/charts/what.png

I cannot believe this is an issue but: test has Intel Inside, production
runs with an AMD processor.
