什么可能导致jruby中的“IOError（封闭流）”？

标签： ruby-on-rails tomcat jruby

我花了最近三天试图将一个jruby / rails / couchdb应用程序部署到linux / tomcat环境中。我已准备好拍摄一些东西了。我目前的问题是这个 - 有一个特定的gem，“simply_stored”，作为couchdb的顶级驱动程序。每当我点击触摸这个宝石的应用程序中的代码时，我就会得到这个红宝石的痕迹：

IOError in HomeController#index

closed stream

现在，我最初的反应是它与与couchdb的通信有关。这仍然是可能的，尽管不太可能。指定不存在的地址具有相同的效果。这个库适用于很多人（包括我自己，在我的开发环境中 - os x / WEBRick）。深入挖掘，我发现了一些（相当分散的）类似问题的参考，具有不同的功能。这是一个：what could be causing this rails ioerror closed stream?

有趣的是，在active_support首次加载/处理文件后，这两个错误似乎都在短时间内发生。这个流问题可能与加载ruby文件有关，而不是tcp连接的东西？

我在这里完全不知所措，我们将非常感谢任何帮助。

编辑 ：有趣的新花絮 - 如果使用glassfish而不是tomcat，这个问题会在相同的配置上消失。相同的服务器，相同的战争文件。
