How do I specify host and port when accessing a web service from JAX-WS-generated code?

Question

I have a WSDL file for a web service. I'm using JAX-WS/wsimport to generate a client interface to the web service. I don't know ahead of time the host that the web service will be running on, and I can almost guarantee it won't be http://localhost:8080. How to I specify the host URL at runtime, e.g. from a command-line argument?

The generated constructor MyService(URL wsdlLocation, QName serviceName) doesn't seem like what I want, but maybe it is? Perhaps one of the variants of Service.getPort(...)?

Thanks!

Answer 1

The constructor should work fine for your needs, when you create MyService, pass it the url of the WSDL you want i.e. http://someurl:someport/service?wsdl.

Answer 2

If you have a look in the generated source close to the generated constructor, you should be able to figure out what to put in it from the default constructor, should look something like:

public OrdersService() {
    super(WSDL_LOCATION, new QName("http://namespace.org/order/v1", "OrdersService"));
}

You should be able to find the def of WSDL_LOCATION in the static field further up in the class.
