cannot load Java class org.quartz.spi.JobFactory

[anildigital]

require 'quartz'

NameError: cannot load Java class org.quartz.spi.JobFactory
from org/jruby/javasupport/JavaUtilities.java:54:in `get_proxy_or_package_under_package'

Help.

[ksekhar]

make sure you have quartz jar in your application's lib directory

I'm having the same problem:

@ksekhar, the quartz jars are inside this gem already as far as I can tell. Shouldn't it be loading it from there?

[ksekhar]

The jars that came with the gem dont get included by default you must do something like the following in the environment.rb or .rb file

require "#{Rails.root}/vendor/gems/jruby-quartz-1.2/java/commons-collections-3.2.1.jar"
require "#{Rails.root}/vendor/gems/jruby-quartz-1.2/java/quartz-1.6.4.jar"
require "#{Rails.root}/vendor/gems/jruby-quartz-1.2/java/log4j.jar"
require "#{Rails.root}/vendor/gems/jruby-quartz-1.2/java/commons-logging.jar"

but use this only for development env (prefereably) because those jars will already be loaded once you deploy on Jboss (give the version is greater than 4.2)

Hope that helps

[bjeanes]

Why is that? It seems like this could be done quite nicely by simply having it in your Gemfile and ... done.

It'd be quite easy to modify the load path such that if the deployment environment already contains jars, they get loaded instead.

[ksekhar]

I am not sure why. May be there is a smart way to be able to include those jars automatically, but I doubt that because if its not a .rb, or rake file, I dont think it will be loaded because the framework is all ruby.

I have the same problem. I am importing an ueber JAR in the application.rb in that way: "require "lib/trophic-graph-1.0-SNAPSHOT-all.jar". On my MacBook Air with jRuby it is running perfectly. But on the debian linux server I always get this Exception:

I also tried to use an absolute path by importing the ueber jar. But that doesn't help.
I googled already, but I couldn't find anything.
Any thoughts?
