我正在尝试在GAE中开发Java SOAP客户端。它正在开发（localhost）而非生产（appspot）。 *构建路径中没有添加jar文件。
例外：

大多数开发人员在部署到生产环境时都面临同样的问题：
https://groups.google.com/forum/#!topic/adwords-api/ciSRh-74rAU https://code.google.com/p/googleappengine/issues/detail?id=4910
但在我的情况下，除了JRE，我没有使用任何JARS。
答案 0 :(得分：1)
挖洞后我知道gae在jax-ws包里找到了一些白名单课。
原因：
javax.xml.ws.Service在内部调用javax.xml.ws.spi.Provider.provide（）方法。因为它将使用com.sun.xml.internal.ws.spi.ProviderImpl类从FactoryFinder创建一个Provider变量。但是在gae中，ProviderImpl并未列入白名单，因此我们无法使用jax-ws创建webService客户端。
解决方案：
Apache Axis正在使用jaxrpc，它与gae兼容。使用apache轴从wsdl生成WebService将解决此问题。
