java - Web服务客户端类作品；但在 servlet 中使用时出现部署错误

Question

我正在使用 JDeveloper 12c 从 WSDL 文件生成“Web 客户端和代理”。它运行良好并生成了一个 Client 类来测试服务的调用。这个客户端工作正常。

然后我生成了一个测试 servlet 并确保它正常工作。

我将相同的 Web 服务调用代码粘贴到一个 servlet 中，在部署时我遇到了这个异常:

我在 Google 上没有得到很多有用的结果。你能帮忙吗？谢谢!

将 metro-default.xml 放在 WEB-INF/classes/META-INF 中可以解决问题。由于引入了基于 Tube 的消息传递，需要 jaxws-ri-2.2.8 jar 才能使 Web 服务正常工作。
