R – Consuming a Web Service written in VS2008

If you go directly to the asmx url with a web browser, and then click on the method you want to call, what's the SOAPAction that they want?

next, check the Reference.vb code and see what the SoapDocumentMethodAttribute attribute is set to.

Do they match?

First question: is this a SOAP or a REST based Java service you're trying to call?

Right now, with the "webHttpBinding", you're using a REST-based approach. If the Java service is a SOAP service, then you'd need to change your binding to be "basicHttpBinding" instead.

IF it's a SOAP based service, you should try this:

BasicHttpBinding binding = new BasicHttpBinding();

binding.SendTimeout = TimeSpan.FromSeconds(25);

binding.Security.Mode = BasicHttpSecurityMode.Transport;
binding.Security.Transport.ClientCredentialType = 
                              HttpClientCredentialType.Basic;

EndpointAddress address = new EndpointAddress(your-url-here);

ChannelFactory<MyService> factory = 
             new ChannelFactory<MyService>(binding, address);

MyService proxy = factory.CreateChannel();

proxy.ClientCredentials.UserName.UserName = "username";
proxy.ClientCredentials.UserName.Password = "password";

I've used this with various web services and it works - most of the time.

If that doesn't work, you'll have to find out more about what that Java webservice expects and how to send that relevant info to it.
