java - JAXB 转换在 Mule 中不起作用

Question

我正在按照 Mule 教程来执行 JAXB 转换。我得到的异常跟踪如下，然后是我的配置

我在 JDK 1.7 上使用 Mule 3.6.2 EE

我的包结构如下所示

Answer 1

eclipse(mule studio)中的Mule项目是Java项目类型的扩展。 Java 项目中的所有资源都必须位于资源类型的类路径条目中，简而言之，src/main/resources 是这些类型的文件必须存在的位置。您可以在那里创建一个包并放置资源，它应该可以工作。

对于 Maven 来说也是如此，Mule 项目从中获得了结构。
