问题描述
我正在尝试在GAE中开发Java SOAP客户端.它正在开发(本地主机)上工作，而不是在生产(应用程序)上工作. *在构建路径中未添加任何jar文件.
I'm trying to develop a Java SOAP client in GAE. It is working in development(localhost) not on production(appspot). * No jar files are added in build path.

大多数开发人员在部署到生产环境时都面临相同的问题:
Most of developers are facing the same issue when they deploy to production:

但就我而言，除了JRE，我没有使用任何JARS.
but in my case I'm not using any JARS apart from JRE.
推荐答案
在挖洞一天之后，我认识到gae在jax-ws软件包中找到了一些白名单类.
After digging hole day i came to know gae found some whitelist class inside jax-ws package.
原因:
javax.xml.ws.Service内部调用javax.xml.ws.spi.Provider.provide()方法.这样，它将使用com.sun.xml.internal.ws.spi.ProviderImpl类从FactoryFinder中创建一个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.
javax.xml.ws.Service calls internally javax.xml.ws.spi.Provider.provide() method. In that it will create a Provider variable from FactoryFinder using com.sun.xml.internal.ws.spi.ProviderImpl class. But in gae ProviderImpl is not white listed so we can't able to create webService client using jax-ws.
解决方案:
Apache Axis使用jaxrpc，并且与gae兼容.使用apache轴从wsdl生成WebService将解决此问题.
Apache Axis is using jaxrpc and it is compatible with gae. Generate WebService from wsdl using apache axis will solve this problem.
