Looks like you need to sign you message using The WS-Security standard. The WS-security standard does not specify any security mapping to wsdl file. Some application use WS-Security policy and WS-Policy Attachement in conjunction with Ws-security.
WS-Policy Attachment does specifies the way to map policies to WSDL.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
