org.jruby.rack.RackInitializationException: while deploying JRoR-App

Hi there,

I have a little rails-app which tries to load several Javaclasses to
work with them. The Java classes are located in my lib/java directory in
a Jar-File.
Warbling runs without any problems. While deploying the war file in
glassfish (v3 build 74.2) I get the following error (anonymized with
***.***).
My environment: Rails 2.3.5, JRuby 1.4, jruby-rack 0.9.5 (tried also
with 0.9.6)

The whole stacktrace is longer. If anyone needs it, please tell me.
My application is quite empty. There is only a model which tries to load
the Java classes (anonymized with ***.***):

Dir[File.dirname(FILE) + 'lib/java/.jar’].each {|jar| require jar}
import Java::de.
**.***.SecurityManager

These few lines let the deploy process fail. Does someone know what I
can do?

kind regards,
marco

My only guess is that your Java classes are not getting loaded
somehow. If you put your jar files directly in WEB-INF/lib you won’t
need to require them and might have a better chance of importing the
classes. My suggestion would be to check paths, class paths, class
loaders, war packages (deployed and exploded) to make sure everything
is where you think it is.
