由于标题指示我有一个Windows服务托管的WCF服务。当我使用Visual Studio WCFTestClient时，它的GetVersion（）方法（它只是返回一个字符串）工作正常。当我尝试从Java客户端调用相同的方法时，我得到一个无效的主机名错误。Windows托管的WCF服务返回400错误的请求无效的主机名到JAVA客户端
使用Wireshark的我跟踪的XML消息，并得到如下：
------- ---------发送

我与主机参数发挥各地，使用S erver的完整DNS名称，但结果相同。这是配置文件：
-----配置------

我使用Java客户端NetBeans和代码是直截了当：
- ----- Java代码--------
CommunicatorService service = new CommunicatorService();
ICommunicatorService port = service.getBasicHttp();
((BindingProvider)port).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "http://192.168.201.210:7770/CommunicatorService.svc");
String version = port.getVersion();
任何指针/调试技巧都会有所帮助。我对Java并不熟悉，所以我不确定从哪里开始，但似乎发送的消息中有些内容是错误的，我可以更改消息或服务的配置以知道期望的内容，我只是不知道那是什么。
在此先感谢！
似乎是网络问题而不是WCF。你是从不同的机器运行java代码吗？检查网络和IIS设置。 – 2013-03-01 22:28:14
