Can not call Java WSDL-WebService from C#?

[Dominik]

Hi there!

I am trying to invoke a method of a webservice that was created in
java. they provided a java client to test the service and everything
is fine, but I actually prefer C# So I add a reference to this
webservice:
http://wortschatz.uni-leipzig.de/axis/servlet/ServiceOverviewServlet


Regarding to the description at http://wortschatz.uni-leipzig.de/Webservices/
I have to set "anonymous" as user and password. As the service itself
doesn't provide parameters for that, I added it as ClientCredentials
like this:

Baseform.BaseformClient baseForm = new Baseform.BaseformClient();
baseForm.ClientCredentials.UserName.UserName = "anonymous";
baseForm.ClientCredentials.UserName.Password =
"anonymous";
baseForm.Open();


Which worked fine so far, but I am not able to a call the method,
because it always tells me that I have to enter a username as well
(altough I do with the ClientCredetials).

My guess is that there are some interop problems with Java WebServices
and C#, as I can proove that the service itself works, I would like to
know, how I can manage to call the service from C#??

Thank you,
Dominik

I assume you are using WCF (System.ServiceModel namespace)? Then Open()
doesn't trigger any communication, only the first call will, so the
behavior you experience is just natural.

Do you specify the "security" setting anywhere? With a BasicHttpBinding
(SOAP 1.1), this defaults to "none", so your username and password will
never be used. Try setting it to "Message" (or, maybe, "Transport" if
the service requires it, but i doubt that).

I tried a WCF Service and a SOAP Service. Unfortuantelly I can not
tell exactly it requires this username and password, because the Java
Testclient that you can download from
http://wortschatz.uni-leipzig.de/axis/servlet/ServiceOverviewServlet
does somehow NOT trigger Fiddler to log the call, so I can not
reproduce it :-(

Is it working with you?

I also found an implementation using PHP, which looks pretty simply:
$client = new SoapClient("http://wortschatz.uni-leipzig.de/axis/
services/$service?wsdl", array('trace'=>1, 'exceptions' => 0,
'login'=>'anonymous', 'password'=>'anonymous'));

$result=$client->execute($request);

and setting the name BUT it claims to have also a transport security

and HTTPS, which the service simply doesn't support ....
Can it be that difficult in C#??

thank you,
