Q。如何为请求动态更改Web Service地址？

 （（BindingProvider）proxy）.getRequestContext ）.put（BindingProvider.ENDPOINT_ADDRESS_PROPERTY，...）; 
 

I deployed a JAX-WS Service and use wsimport to generate client code. Because I run wsimport on localhost, I got the client code with binind on "localhost" address.

But I want to reuse those client code on other computers which access my deployed service with a public IP y.y.y.y. How can dynamically use those (once) generated client code to access my service. (The ip of service may change...)

This is covered in the FAQ of JAX-WS:

((BindingProvider)proxy).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "...");
