SOAP Messages
A SOAP message is an XML document transmitted from a sender to a receiver. It is basically a one way transmission between different nodes, but it could be combined by an application to implement more complex interaction patterns.
The following is an example of the basic structures in a SOAP message:
<?xml version="1.0"?> <env:Envelope xmlns:env = "http://www.w3.org/2003/05/soap-envelope" <env:Header> </env:Header> <env:Body> <env:Fault> </env:Fault> </env:Body> </env:Envelope>
