Apache CXF Client for Dynamic Endpoints

This worked for me.

String customerEndPoint = "https://localhost:8080/customerService/v1"

customerWebService = service.getCustomerWebServicePort();

((BindingProvider) customerWebService).getRequestContext()
                        .put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
                                customerEndPoint);

Working in cxf 2.6.1

Client client = ClientProxy.getClient(port);
client.getRequestContext().put(Message.ENDPOINT_ADDRESS, "http://some-valid-endpoint") ;

Try the following:

MyWebServicesSoap port = service.getMyWebServicesSoap12();
BindingProvider provider = (BindingProvider) port;
provider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, endpoint); 

Alternatively, MyWebServices might have other getXXX methods that take a URL for the WSDL location
