我正在尝试从我已经创建的 WSDL 定义中生成 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

(耶〜冗长)

我正在使用基于 Eclipse 3.6.1 的 MuleStudio 1.3.0。我已经尝试从 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。

我该如何解决这个问题?

以下是我的 wsdl 文件供参考:

我会尝试从命令行直接在 Wsdl 上调用 jaxws wsimport 命令。我相信它现在随 JDK 一起提供,因此您甚至不必下载它。
您可能遇到了已在更高版本的 wsimport 中修复的错误。
