我正在阅读 Gilberto T. Garcia Jr 的 Lift Application Development Cookbook，遇到了一个我似乎无法解决的问题。我已经复制了源代码 Chap06-map-table，我正在尝试修改它以与我的 IBM i（iSeries、AS/400、i5）数据库一起使用。我能够使用 Squeryl Record 使其与第一种类型的连接一起工作。但是，我似乎无法弄清楚如何使用 JNDI 数据源使其工作。我花了几天时间在 Internet 上搜索设置示例，但没有找到涉及 DB/400 数据库连接的好示例。以下是我尝试启动容器时遇到的错误以及我为使其工作而修改的代码。任何帮助，将不胜感激。jt4oo的数据源类似乎有一些选择。jar (jtOpen)，我不确定哪个是最好用的，或者可能还有另一个。我一直在尝试这三个中的每一个，并假设第一个是正确的。
