How to use a web service wsdl

Hello,

How do I use a web service being provided by another software? The service is supposed to be used on a dynpro dc project.

I noticed that when creating a model, i choose adaptive web service, since the other web service is already deprecated. The service provider exposes a wsdl, but not a wsil, and requires a username and password to use the wsdl.

When i try to use the wsdl, it gives me an error of authentication failing. I could not use the other option as the service provider does not support wsil.

Is there a way around this? thanks.

regards,

arnold
