=HowTo? process an incoming ebXML message=

Some thoughts:

• is it HTTP
  • does it have the SOAPAction?
• get the ebXML message (that is without payloads)
• check it against a standard ebXML Message
  • is it well formed?
  • is it XML schema valid (time consumig but generally a good task)
  • is it a ebMS signal?
    • is it a known ebMS signal
  • is it a user message?
    • are payloads present?
• check it against ebXML CPA
  • does the CPA support this message?
    • does the Service/Action exist?
  • are the from and to OK?
  • are the reliable messaging characteristics OK?
  • are the security characteristics OK?

• if it is signed?
  • validate signature
• if it is encrypted?
  • decrypt it

• if it is a ebMS signal
  • if it is a PING
    • create the PONG
  • if it is a Message Status Request
    • create the Message Status Response
  • if it is an ERROR
    • ???

• is it relialble messaging?
  • is it duplicate elimination?
  • provide reliable messaging

• if it is a user message
  • creating incoming directive
  • copy payloads
  • copy directive
