How to send a signed SOAP message with additional HTTP Header fields

Question

Our Partner's integration requirements are that we send them asynchronous SOAP messages, that are digitally signed, and whose HTTP headers contains 5 or 6 additional header fields, of which 3 or 4 will need to be dynamically set during the message mapping.  I believe we can use the HTTP adapter for adding new fields to the HTTP header, but don't believe it supports signing.  I believe that the SOAP adapter supports signing, but I'm not clear on how to use it to add fields to the HTTP header.  What is the most straight-forward way to achieve both the signing of the message and the addition of the HTTP header values?
Thanks,
Kurt

>>>What is the most straight-forward way to achieve both the signing of the message and the addition of the HTTP header values?
Use Java mapping for both.
1) Signing the message
You can digitally sign the soap message using many standard api like WSS4j? or  refer Java XML signature API which comes in Jdk1.6.
Refer these links
WSS4J  -  http://ws.apache.org/wss4j/axis.html
Java XML signature : http://java.sun.com/developer/technicalArticles/xml/dig_signature_api/
2) >>whose HTTP headers contains 5 or 6 additional header fields, of which 3 or 4 will need to be dynamically set during the message mapping
Use Dynamic configuration API to set the additional header fields during message mapping.
