JRuby Cassandra问题

Question

我正在使用Jruby连接Cassandra和红宝石。我正在开发一个代码，它必须与Rails中的cassandra进行交互。我已经配置并安装了jruby。我也为cassandra和jruby的所有依赖做了“导入”。运行文件时遇到问题。我得到这样的错误。

============================================== ====================================

任何人都可以帮助我解决这个问题吗？

你可以发布你的代码，它很难从堆栈跟踪调试。

它看起来像你正在使用原始节俭，有一个jruby wrapper为java cassandra客户端库hector将更容易使用。
