我正在使用 IBM RAD Eclipse 的 Web 客户端生成工具进行 Web 服务。在所有生成的类中，我在开头都有以下评论。
//
// Generated By:JAX-WS RI IBM 2.1.1 in JDK 6 (JAXB RI IBM JAXB 2.1.3 in JDK 1.6)
//
我将生成的项目导出到 JAR 文件，然后将其添加到我的 EAR。当我从我的 Web 应用程序使用客户端存根调用 WebService 时，我得到以下异常：

这个 WSATGenerator 是什么，它应该在哪个 jar 中可用？它是 WebSphere 上的标准库，还是必须手动配置？
谢谢
