Changing the URL on a webservice client generated with wsimport

Question

I am trying to write a module for a Java application that accesses a WSDL-described webservice. The source WSDL was downloaded straight from what I believe to be an ASP.NET

Answer 1

This approach requires me to also supply a javax.xml.namespace.QName object, which I don't yet understand, as the second argument.

Copy the one from your generated source. A QName is an XML qualified name - a "unique" identity.

I still don't understand why the WSDL is needed at runtime.

I can't say I know for sure, but a WSDL is basically a schema. By providing it, I'm guessing you give JAX-WS a mechanism to validate the SOAP response. I don't think the JAXB bindings are enough to do this.

I always use the two-argument constructor in the generated service to provide a URL via the ClassLoader.getResource method to embed the WSDL in my jar. As with any schema, using a remote or file system URL for this is stupid less than optimal.

See this question for how to set the end-point at runtime:

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);
