Web服务客户端类起作用； 但是在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类来测试该服务的调用。 该客户端工作正常。

然后，我生成了一个测试servlet并确保它可以工作。

我将相同的Web服务调用代码粘贴到Servlet中，并且在部署时遇到了以下异常：

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中可以解决此问题。 引入基于Tube的消息传递后，需要jaxws-ri-2.2.8 jar才能使Web服务正常工作。
