.NET Forum / ASP.NET / Web Services / December 2007ASP.NET Web Service?
Hello, I have this project where I am creating a ASP.NET Web service that's going to be consumed by an application on the Intranet. This Web service will access a SQL Server database, extract data from tables, create XML DOM that's going to be posted to 3rd party Internet Web service. I have a couple of questions. 1) If I have the user ID and PSW blah, blah for this site and the URL, how do I present credentials to the 3rd party Web Service from my Web service? I do have (URL?) WSDL that I generated so that I can from a test URL 2) If I can login to the 3rd party Web service how do I post the XML to the 3rd party Web service? I have the XSD(s) for the 3 types of XML(s) that I am suppose populate and transmit to the 3rd party Web service. I found this link that's talking about the tool to take a XSD and generate the classes from them so you can come out with a serialized XML to be transmitted once populated. Is this a good approach to take? <http://www.microsoft.com/downloads/details.aspx?familyid=89e6b1e5-f66c-4a4d-933b -46222bb01eb0&displaylang=en> What I need is some good links with examples on how to do this on how to make the contact with the Web service and post XML to a Web Service. If you can provide some examples, it would be much appreciated. > Hello, > > I have this project where I am creating a ASP.NET Web service that's I'm not clear why you are posting this to a classic ASP group (.asp.general).

If this is not the correct NG, then I'll find the correct one to post my questions. I know how to consume the one I am creating for the Intranet. It's the Web service at the 3rd party site I am concerned with consuming from my Web service. >>> Hello, >>> [quoted text clipped - 7 lines] > about ASP classic, but rather it's ASP.Net.

Hopefully, their documentation will tell you what they require. > 2) If I can login to the 3rd party Web service how do I post the XML to > the 3rd party Web service? Your web service will be a client to the 3rd party service. Simply use Add Web Reference to add a reference to their service into your project. You'll then be able to issue calls to their service from your service. > I have the XSD(s) for the 3 types of XML(s) that I am suppose populate and > transmit to the 3rd party Web service. > > I found this link that's talking about the tool to take a XSD and generate > the classes from them so you can come out with a serialized XML to be > transmitted once populated. That will probably not be necessary at all. Add Web Reference will create a proxy class that can be used to talk to their service. It will also produce proxy classes for all of the complex parameters to their service. It is these other proxy classes that you'll be able to fill in, then call their service just like it was "normal" code. > Is this a good approach to take? > > <http://www.microsoft.com/downloads/details.aspx?familyid=89e6b1e5-f66c-4a4d-933b -46222bb01eb0&displaylang=en> > > What I need is some good links with examples on how to do this on how to > make the contact with the Web service and post XML to a Web Service. The reason you won't find many examples is that none are really needed. Any example you find on how to consume a web service will be all that you need. There's nothing special about consuming a web service from inside of a web service.

If not, you're going to have to build the XML file from scratch (i.e. with your own code rather than pre-generated code).

I know that the user-name and psw has to come in a SOAP message, so I'll have to figure that out. About the XML, I was looking to create a dataset off of the XSD, but loading it into a data.set, an error occurred stating that another schema is involved, an include, and it doesn't know about it, which is a *Types* schema. I have been in contact with the 3rd party vendor. The vendor is going to have to give me more information on how to consume their service too. I'll hate having to build the XML manually, and I will certainly be looking for better ways to do this. I have also found out about this .Net Framework XSD utility that will create a dataset from the XSD. Maybe, I get an email from the vendor with what I need. I didn't go to work today due to other business matters. It may come down to making a class and serialize it down to XML.
