錯誤上使用JRuby

Question

與我的應用程序與鶯建JBoss的開始，當我得到這個錯誤機架初始化：

Error: unable to initialize application 
org.jruby.rack.RackInitializationException: wrong number of arguments (1 for 0) 

調用堆棧：

任何想法？

Answer 1

我們在Rails 3.0.11/JBoss 5和最新的jruby-rack上遇到了同樣的問題。 排序了這一點，我們不得不使用JRuby的機架1.0.10

請嘗試把此行到您的Gemfile：

gem 'jruby-rack', '1.0.10' 

Answer 2

我得到了同樣的錯誤升級應用到Rails 3時問題與調用ActionController::Base.relative_url_root=有關，應該發出棄用警告，但它在Rails 3.0.10中被破壞。

我的解決方案是升級到jruby-rack 1.1.4和rack 1.2.5。
