使用Warbler創建jRuby 1.9 Sinatra應用程序無法啓動

我有一個簡單的Sinatra應用程序，我將作爲戰爭在tomcat中託管。當我在warcat中運行它並在tomcat中運行它時，一切正常。如果我設置了Ruby 1.9的國旗在我顫聲配置使用Warbler創建jRuby 1.9 Sinatra應用程序無法啓動

config.webxml.jruby.compat.version =「1.9」

那麼戰爭不跑，我在tomcat日誌中出現此錯誤

mysinatraapp.rb文件在戰爭中，所以我不明白爲什麼它找不到它。從jruby的命令行運行時，應用運行良好，所以我不認爲這是我的代碼和1.9的兼容性問題。即使只是從web.xml刪除這些行

<context-param> 
<param-name>jruby.compat.version</param-name> 
<param-value>1.9</param-value> 
</context-param>

將讓應用程序啓動正常。

我罐子的版本是 JRuby的核心1.6.5.1.jar JRuby的機架1.1.3.jar JRuby的STDLIB-1.6.5.1.jar

我認爲這是可以解釋的通過1.8和1.9之間的負載路徑行爲（MRI也是如此，不僅僅是JRuby）的微妙變化。證人：

$ jruby -v -rpp -e 'pp $LOAD_PATH' 
jruby 1.7.0.dev (ruby-1.8.7-p357) (2012-01-12 0e83d96) (Java HotSpot(TM) Client VM 1.6.0_29) [darwin-i386-java] 
["/Users/nicksieger/Projects/ruby/jruby/lib/ruby/site_ruby/1.8", 
"/Users/nicksieger/Projects/ruby/jruby/lib/ruby/shared", 
"/Users/nicksieger/Projects/ruby/jruby/lib/ruby/1.8", 
"."] 

$ jruby -v --1.9 -rpp -e 'pp $LOAD_PATH' 
jruby 1.7.0.dev (ruby-1.9.3-p6) (2012-01-12 0e83d96) (Java HotSpot(TM) Client VM 1.6.0_29) [darwin-i386-java] 
["/Users/nicksieger/Projects/ruby/jruby/lib/ruby/site_ruby/1.9", 
"/Users/nicksieger/Projects/ruby/jruby/lib/ruby/shared", 
"/Users/nicksieger/Projects/ruby/jruby/lib/ruby/1.9"]

所以你可能要明確地添加'.'或$servlet_context.getRealPath("/WEB-INF")裏面config.ru負載路徑。
