java - overriding or setting web service endpoint at runtime for code generated with wsimport

Question

Using code that was generated with wsimport, can the service endpoint be overridden without having to regenerate the code?

I have written a simple java webservice, following are the steps:

1. I compile the java class and generate a war file
2. Deploy the war file to my app server (tomcat)
3. Access the WSDL via the URL e.g. localhost:8080/service/helloservice?wsdl
4. use the URL with wsimport.bat to generate client classes for example: wsimport http://localhost:8080/service/helloservice?Wsdl
5. I use those classes in my client app to call the service

The problem is that is the service is deployed on an app server running on port other than 8080, the communication between client and service never happens. I am trying to know what is the best way to create stubs that does not have server and port hardcoded in the stub used by the client.

Your client can set the end-point in the service "port" at runtime via the BindingProvider interface.

Consider the JAX-WS client in this JAX-WS tutorial. Another way to write this code would be:

HelloService service = new HelloService();
Hello port = service.getHelloPort();
BindingProvider bindingProvider = (BindingProvider) port;
bindingProvider.getRequestContext().put(
      BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
      "http://foo:8086/HelloWhatever");
String response = port.sayHello(name);

Caveat: I haven't downloaded the tutorial code and tested this code against it.
