在将 Rails 3.2 项目部署到 Weblogic 10.3 时遇到此问题，并正在寻找一个简单的答案。

环境如下所示：JRuby 1.7.2、JRockit 1.6、Rails 3.2.9、Warbler
我部署了基本 2 模型加上设计用户项目，当我在浏览器中浏览它时会发生此错误。有没有人见过这个？这是我第一次使用 JRuby。
编辑：
添加我最近失败的尝试。请注意，我已经为 1.6.8、1.7.0、1.7.2 尝试过 jruby、jruby-jars 并且没有成功。这是我的 Gem File 和 Warbler 配置：
#source 'https://rubygems.org'
source "http://bundler-api.herokuapp.com"
gem 'rails', '<3.3'
# Bundle edge Rails instead:

# in production environments by default.
group :assets do

end
和 Warbler Config（使用 Warble War）：
class Warbler::Jar
def replace_compiled_ruby_files(config, compiled_ruby_files)
config.excludes += compiled_ruby_files
compiled_ruby_files.each do |ruby_source|
files[apply_pathmaps(config, ruby_source, :application)] = StringIO.new("load __FILE__.sub(/\.rb$/, '.class')")
end
end
end
Warbler::Config.new do |config|
config.dirs = %w(app config lib log vendor tmp)
config.webxml.jruby.compat.version = "1.9"
end
