最近用JAX-WS2.0开发一个WebService 客户端，访问普通http没有什么问题，但当访问 HTTPS时老是提示 HTTP transport error: Connection refused的错误，如下：
Exception in thread "main" com.sun.xml.internal.ws.client.ClientTransportException: HTTP transport error: java.net.ConnectException: Connection refused: connect

我用Myeclipse10 带的“Test with Web Services Explorer”工具或SOAPUI工具测试，不管是HTTP还是HTTPS都可以得到正确的结果，就觉得奇怪了，到底哪里出了问题。
后来google 了一把，发现以下2篇文章，比较有用
https://www.java.net//node/666240
https://community.jboss.org/thread/204961?_sscc=t
文中都提到了要 覆盖 BindingProvider.ENDPOINT_ADDRESS_PROPERTY，
修改了代码，问题解决。
如：
String wnsaddr = "https://www.xxx.com/ws/"
One_Service service = new One_Service();
Wsport port = service.getPort(Wsport.class);
((BindingProvider) port).getRequestContext().put(
BindingProvider.ENDPOINT_ADDRESS_PROPERTY, wnsaddr);
port.dosomething();
