Dear JRubyists,
i’ve got a complex JRuby app that works fine on my local machine.
However, when i war it up and deploy it, it mostly runs – except
exercising certain code paths are causing a class not found error.
The class is in a jar in the war file. Moreover, the jar is found by a
require statement in one of my controllers. However, when the class in
needed in some Java code that JRuby calls, the class not found error is
thrown.
i believe this might be caused if the jar is not actually on the JVMs
classpath for the instance of JRuby running. How would i confirm or deny
that it’s only the JVM’s classpath, and if it’s not get it on?
Best wishes,
–greg
Dear JRubyists,
i can verify that the jar containing the class that is not found is
actually in WEB-INF/lib. According to the wiki on WAR files, WEB-INF/lib
should be on the class loader’s path. So, i’m mystified.
Best wishes,
–greg

CNFEs can also be caused by two copies of a class being loaded –
make sure there’s only the one instance.
Also, what server and JVM are you running this on?

without understanding the whole lot in details I would remove the
“require of that jar” from the controller. you have it already in WAR
classloader and that should be sufficient to find any java class for
jruby.
