使用Warbler和降級的JRuby-Rack時發出加載第三方JAR的問題？

Question

我們使用Warbler將應用程序部署到JBoss。服務器似乎開始罰款，但是當一個請求被髮送到我們得到以下錯誤的應用程序：

... 
JRuby-Rack startup 
    No such file to load -- lib/mylib 
.... 

正如你可以看到它似乎在嘗試加載mylib.jar，這是什麼時候被撞車出局我們在user.rb類中使用的Java庫。我檢查了三倍，mylib.jar文件存在於myapp/lib目錄中，並且它被Warbler（它存在於WEB-INF/lib/mylib.jar中）成功打包。

請注意：我將JRuby-Rack降至1.0.10後，遇到此處詳述的問題 - NoMethodError: relative_url_root when deploying rails app on tomcat。所以或許這個問題與此有關？

我不知道發生了什麼事情。有任何想法嗎？

可能證明是有用的其他詳情：

Java Version: 1.6.0_22 
JRuby Version: 1.6.5 (ruby-1.9.2-p136) 
Ruby Language Level: 1.9 

的Gemfile：

gem 'rails', '3.1.1' 
... 
gem 'warbler' 
gem 'jruby-rack', '1.0.10' 
... 

配置/ warble.rb：

... 
config.dirs = %w(app config lib log vendor tmp) 
... 
config.webxml.jruby.compat.version = "1.9" 
... 

應用程序/模型/ user.rb：

require 'java' 
require 'lib/mylib.jar' 
...

Answer 1

你怎麼樣需要你的罐子。

，如果它是

require 'lib/myjar' 

嘗試將其更改爲

require 'myjar' 

，並看看是否能工程
