Jruby on mogrel does not find java-classes in jars!

Ruby JRuby
1

Hello!

I deployed a Jruby-On-Rails-Application on mongrel. The rails-part works
fine, but as soon as I try to call the include_class-method, it does not
find the required java-class, loaded from a jar (jruby does include it
in the classpath). Suprisingly, the java-package works fine in the same
code (for example java.lang.System.out.println “hello from java”) …

require “java”
require “#{RAILS_ROOT}/lib/checkout/checkout.jar”
require “#{RAILS_ROOT}/lib/checkout/svnkit.jar”
include_class “checkout.Files” <-- exception

Files.main main_args.to_java :String

Maybe someone can help me!!! Thanks in advance …

Solved - I used the rails version 2.1.0 and it just works … :slight_smile:

Well, it stopped working and I don’t know why … :frowning:
