I'm trying to consume a WebService written in Java by our provider from our C# App. When it's time to communicate, I get this:

> 
> WSDoAllReceiver: Incoming message does not contain required Security header
> 
> 
> 

Since yesterday I'm trying to find out how to add security header to a SOAP message.

Yes, I read this ( [Clueless about how to create SOAP <wsse:Security> header](https://stackoverflow.com/questions/734355/clueless-about-how-to-create-soap-wssesecurity-header) ) but it did not work.

I looked around and this seems to be a rather asked question. I wonder if I can get some help here, some pointers, some code, to get me started.
