java - 生成 JAX-WS 源 NullPointerException

Question

我正在尝试从我已经创建的 WSDL 定义生成 Java 服务类。我当前的问题是它失败并显示以下消息，仅此而已:

Unable to generate JAX-WS Source.

Reason:
java.lang.NullPointerException

(是的~冗长)

我使用的是MuleStudio 1.3.0，它基于Eclipse 3.6.1。我尝试过从 Mule 的组件和直接从 WSDL 创建这些类，但我得到了同样的错误。

我故意混淆了 WSDL，它正确地开始抛出验证错误。这意味着它正在读取文件并正确解析它。不知道接下来会发生什么。

我该如何解决此问题？

下面是我的 wsdl 文件供引用:

我会尝试从命令行直接在 Wsdl 上调用 jaxws wsimport 命令。我相信它现在已经随 JDK 一起提供了，所以您甚至不必下载它。
您可能遇到了一个错误，该错误已在 wsimport 的更高版本中修复。
