java - 向 Mule 流添加新组件时出现命名空间问题

Question

我是 Mule 新手，每当我将带有固定频率调度程序的“轮询”添加到 Mule 流中时，都会出现命名空间错误。每当我们添加新组件以流经编辑器时，Mule 不应该继续添加命名空间吗？我是否明确添加了与“poll”相关的命名空间？我期待 Mule 核心中可以使用 poll 的命名空间。我正在使用 Mule studio-3.5.0。

这是 mule 配置 -

编辑:根据 David 的建议，我尝试按照 Mule documentations 添加 Mule 3.5.0 运行时但我没有找到 3.5.0 Cascade 或 BigHorn。

Answer 1

固定频率调度程序位于 Mule 核心中，但属于 Mule 3.5.0 Cascade 或 BigHorn，而不是您当前使用的 3.4.1 EE。

切换到这两个运行时之一，它就会工作。
