How To Develop a Simple WebService App XI Scenarios

Question

Hi,
How can I develop A simple Webservice for any scenario, for example, if am doing File to file scenario, and i want to develop a Webservice for the same scenario,
I think in ID we have an option Under Tools "Define Webservice" where in we can use wsdl format of the message interfaces.
How should i proceed to develop the Webservice?

Hi Varun,
After creating the wsdl file u can deploy using MS visual studio.
Follow the steps and run the scenario.
use it in a Client Program in .NET : (assuming Maths as the WSDL and Webserice name)
1.) Place maths.wsdl in C:/Sample/ folder
2.) Open Visual studio command prompt using the Start Menu
        Start->Programs->Microsoft Visual Studio 2005->Visual Studio Tools->Visual Studio 2005 Command Prompt
3.) In the Command prompt go to that directory
    > C: 
    > CD\
    > CD Sample
    > wsdl maths.wsdl /out:"c:\sample"
4.) The previous step will create a file called Maths.cs , go to that folder and confirm this
5.) Open Microsoft Visual Studio 2005, open the Client application where this webservice needs to be called
6.) If your Client application is a web application, the see if the website has a folder called "App_Code"
    If not then create this folder. Right Click on this folder and click on "Add Existing Item"
7.) Browse to C:/sample and select the Maths.cs file
8.) If your client is a Desktop application , just add this file in a similar manner to the project(no need of creating any folder)
9.) After the file gets added, open Maths.cs file
10.) Add a namespace to it for convinience
        eg:
            namespace SAP
   This should come before the Class Declaration and close it after the class
    eg: See the red lines
    namespace SAP
    /// <remarks/>
    [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")]
    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [System.Web.Services.WebServiceBindingAttribute(Name = "Equi_get_NotifBinding", Namespace = "http://Equipment_Get_Notifications")]
    public partial class Equi_get_NotifService : System.Web.Services.Protocols.SoapHttpClientProtocol
      functions....
11.) Save the Maths.cs file
12.) Open the Webform or windows form code where this webserive will be called
13.) The webservice will now be available here under the SAP namespace
        so when u type "SAP." u will get all the classes in it.
        Add credential in this code as shown below
    eg:
    private void GetNotifications()
        try
            SAP.Equi_get_NotifService ser1 = new SAP.Equi_get_NotifService();       //This is the Webserive Proxy class
            SAP.Equi_get_Notif_Request req = new SAP.Equi_get_Notif_Request();      //Request Class
            req.Equipment = SAPID;
            req.Date = Calendar1.SelectedDate;
            System.Net.CredentialCache ch = new System.Net.CredentialCache();                                    //Adding Credentials for authentication on webservice server
            System.Net.NetworkCredential cr = new System.Net.NetworkCredential("xisuper", "infotech");
            ch.Add(new Uri(ser1.Url), "Basic", cr);
            ser1.Credentials = ch;                // Assing this Credential to the ProxyClass.Credentials property as shown here
            SAP.Equi_get_Notif_ResponseNotifications[] res = ser1.Equi_get_Notif(req);        //Call the webservice, res is the responce object
            GridView1.DataSource = res;
            GridView1.DataBind();
        catch (Exception ex)
            Response.Write(ex.Message);
