How To Pass In SOAP Header For XML Datasource

Hi,



I have created a simple webservice with a soap header and am trying to
access it using an xml datasource in reporting services. The query
works but I have no idea how to pass in a value for the UID on the host
header. Any help? what XML would I add for the header?



This is what I have no that allows me to pass in parameters through the editor.

<Query>

<Method Namespace="http://tempuri.org/" Name="HelloPerson2"/>

<SoapAction>http://tempuri.org/HelloPerson2</SoapAction>

</Query>



Here is the code for the webservice:

/// <summary>

/// Summary description for WebService

/// </summary>

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

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



public WebService () {



//Uncomment the following line if using designed components

//InitializeComponent();

}



[Serializable]

public class PersonHeader : SoapHeader

{

private int _uid;

public int UID

{

get { return _uid; }

set { _uid = value; }

}

}



public PersonHeader userCredentials;



[WebMethod]

[SoapHeader("userCredentials")]

public Person HelloPerson2(string firsName, string lastName)

{

Person person = new Person();

//person.FirstName = "John";

//person.LastName = "Smith";

person.FirstName = firsName;

person.LastName = lastName;

person.UID = userCredentials.UID;

return person;

}



[Serializable]

public class Person

{

public Person()

{

}

private string _firstName;

public string FirstName

{

get { return _firstName; }

set { _firstName = value; }

}

private string _lastName;

public string LastName

{

get { return _lastName; }

set { _lastName = value; }

}

private int _uid=1000;

public int UID

{

get { return _uid; }

set { _uid = value; }

}

}

}
