Integration

First of all thanks for reading.
I'm new to SOA, and I came from .Net world.
I'm Trying to understand how to set a custom header in my soap call to the webService I've follow the Michael Czapski "Handling SOAP Headers in BPEL" but I can't reproduce that in my own scenario.

Let me explain.
This is the webservice I want to invoke:

public class Service : System.Web.Services.WebService
{

   public MioHeader AHeader = new MioHeader();

    [WebMethod]
    [SoapHeader("AHeader")]
    public string AMethode(string aVar)
    {
        return aVar + AHeader.TokenInHeader;
    }
}

MioHeader is a class with a property Token of type string

Could please someone put me in the right way?

Many regards and sorry for my English, I'm from Italy.
