NoClassDefFoundError for CFCHART

[Yuri]

Hi everyone.

I have a pretty weird question: my CFCHARTs suddenly stopped working
(they worked fine a week ago).
Calling a page with CFCHART in it displays a NoClassDefFoundError
error. Can anyone help me? OSX, Lion, Java 1.6.0_29, Railo Railo
3.3.1.000 final. Nothing has been changed locally since the last week.

Stacktrace:

Could not initialize class railo.runtime.tag.Chart

Are you running Railo on Tomcat? I had a similar issue before with no image manipulation functions working, throwing a similar error. The problem had to do with how Tomcat was started: as a system daemon instead of as a specific user. Due to Apple's java api implementation, some classes are only accessible when java process (tomcat in this case) is run as a specific user OR if java is run in headless mode.

Try this:

- edit (or create) $CATALINA_HOME/bin/setenv.sh script ($CATALINA_HOME is your Tomcat install dir)

- add this line to it:

export JAVA_OPTS="-server -Djava.awt.headless=true"

(or if you already have a JAVA_OPTS line in there, add -Djava.awt.headless=true setting to it.

- restart Tomcat

(PS: in the same line you can include other java-related settings, like -Xms and -Xmx, to optimize memory settings)

I can just say what is happening. Railo tries to load a tag from the core library, but this fails because it was not found. The weird thing is that the tag Railo tries to load and the class that does this try is in the same lib (core). I think it is not a access problem, sound more like a memory problem to me, check your perm gen memory size, in the entry page of the admin.

Thanks a lot!!! Switching to the headless mode did the trick!
