我们正在使用 Warbler 将我们的应用程序部署到 JBoss。服务器似乎可以正常启动，但是当向应用程序发送请求时，我们收到以下错误：
...
JRuby-Rack startup
No such file to load -- lib/mylib
....
如您所见，在尝试加载 mylib.jar 时，它似乎崩溃了，这是我们在 user.rb 类中使用的 Java 库。我已经检查了 mylib.jar 文件是否存在于 myapp/lib 目录中，以及它是否被 Warbler 成功打包（它位于 WEB-INF/lib/mylib.jar 中）。
请注意：在遇到此处详述的问题后，我将 JRuby-Rack 降级为 1.0.10 - NoMethodError: relative_url_root when deploying rails app on tomcat。所以也许这个问题与此有关？
我不知道发生了什么。有任何想法吗？
