Soap message w/http authorization question...

Hello,

I'm new to using WSE and sending SOAP messages - and I'm trying to figure out how to incorporate Http authorization. I am trying to send a SOAP envelope to a web service that requires http authorization and follows basic credential format, and I'm not really sure what I need to do.

I've been looking at the WSE samples from Microsoft, and have an understanding of what I need to do to build the message with the SoapSender & SoapEnvelope classes, but how would I attach the credential/login/password information? Here is what needs to go with the SOAP envelope:

POST /MyLocation/Directory HTTP/1.1
SOAPAction: ""
Authorization: Basic
User-Agent: Java/1.4.2_08
Host: 127.0.0.1:8070
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
Content-Type: application/x-www-form-urlencoded
Content-Length: 366
[SOAP envelope]

Can anyone point me to any samples or information how this would be incorporated into the SOAPEnvelope object?

Thanks for any help,
Greg
