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/axi...verviewServlet <
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/axi...eOverview?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

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:anonymous@...etc...
without success.
Can anyone help me out with this?
Best regards,
Markus
