webservice. using dime with wse2

[Ero]

Hello,

I have a simple webmethod to send Dime attachments using WSE 2 :

[WebMethod]

public void CreateDimedImag e()

{

SoapContext respContext = ResponseSoapCon text.Current; // the problem is
here. I always have ResponseSoapCon text.Current = null.

DimeAttachment dimeAttach = new DimeAttachment( "image/gif",
TypeFormat.Medi aType, "C:\\temp\\help .gif");

respContext.Att achments.Add(di meAttach);

}

when I try to trace this method I see ResponseSoapCon text.Current as
<undefined value>.

when I try to access method using client application, I get Exception:

An unhandled exception of type 'System.Web.Ser vices.Protocols .SoapException'
occurred in system.web.serv ices.dll

Additional information: System.Web.Serv ices.Protocols. SoapException: Server
was unable to process request. ---> System.NullRefe renceException: Object
reference not set to an instance of an object.

--- End of inner exception stack trace ---

I included this to my web.config :

<soapExtensionT ypes>
<add type="Microsoft .Web.Services2. WebServicesExte nsion,
Microsoft.Web.S ervices2,Versio n=2.0.0.0, Culture=neutral ,
PublicKeyToken= 31bf3856ad364e3 5"
priority="1" group="0"/>
</soapExtensionTy pes>
I heard this can happen because of some security restriction. If so, how can
I check this?
