I am trying to use ActiveMerchant to send credit card transactions to  
CyberSource. I have been trying to follow the documentation, examples,  
and APIs, but problems persist. ActiveMerchant is sending a SOAP  
header and envelope to CyberSource with my credentials, but they are  
being rejected.

To debug this, I would like to observe the actual SOAP that is going  
down the wire. Is there a tool that will let me do that? I am using  
Eclipse/AptanaStudio/RadRails with a Mongrel server.
