SOAP Authorization

Hey there.

I recently stumbled upon the "Projekt Deutscher Wortschatz" (project
german vocabulary) of the Leipzig Univesity, Germany, which is somewhat
similar to Princeton's WordNet project.
The Leipzig University provides a SOAP-based web interface that is
briefly described here >
http://wortschatz.uni-leipzig.de/axis/servlet/ServiceOverviewServlet <

Since I never ever used SOAP programmatically I throught it would be a
nice idea to start right away with the "ServiceOverview" function they
provide.

So I fired up VS and added the WSDL file
http://wortschatz.uni-leipzig.de/axis/services/ServiceOverview?wsdl
as a web reference.

The ping method works fine, but if I execute() the class, a
SoapException is fired stating that I should provide a username.
Since there is no function for that and the Java examples show that they
are not sent as a execute() argument, I'm not sure what to do.

I found a example on the net that introduced a CredentialCache to me,
which I tried to use, without success.

By now the code looks like this:

~~ snip ~~

using System.Net;
using Test.de.uni_leipzig.wortschatz;

namespace Test
{
class Program
{
static void Main(string[] args)
{
ServiceOverviewService sos =
new ServiceOverviewService();

CredentialCache cache = new CredentialCache();
cache.Add(
new Uri(sos.Url),
"Basic",
new NetworkCredential(
"anonymous",
"anonymous"
));
cache.Add(
new Uri(sos.Url),
"Digest",
new NetworkCredential(
"anonymous",
"anonymous"
));
sos.Credentials = cache;

RequestParameter param = new RequestParameter();
param.corpus = "services"; // whatever ...

ResponseParameter response = sos.execute(param);
}
}
}


~~ snap ~~

As I said, the execute() line throws the exception:

~~ snip ~~

System.Web.Services.Protocols.SoapException was unhandled
Message="Please enter a username!"

~~ snap ~~


There are plenty of examples on this using Java or Perl, both give
username and password within a SOAP connection object's constructor -
which I don't have in VS.
I tried to add the authentication to the URL so that it is
http://anonymous:[email protected]...
without success.

Can anyone help me out with this?
Best regards,
Markus

You are using "servlet" I realized. So what web server are you using? IIS?
If you not using IIS then I think it is a bit hard for VS to handle it.

Hi,

It is not /my/ server, but as far as I know, it is driven by Java (on
Apache - but this is an assumption).
