Apache CXF: How to add custom SOAP message headers to a web service request?
SOAP headers can be added to a Web service request in different ways, if you use Apache CXF. They way I prefer is the one I’ve mentioned here – as it doesn’t require changes to wsdl or method signatures and it’s much faster as it doesn’t break streaming and the memory overhead is less.
The headers in the list are streamed at the appropriate time to the wire according to the databinding object found in the Header object.
About SOAP headers,
Like any good messaging protocol, SOAP defines the concept of a message header. It is an optional part of any SOAP message. If it exists, the header contains application-specific information (like authentication, payment, etc) about the SOAP message i.e. information about the message, or about the context in which the message is sent, or basically whatever the creator of the message thought was a good idea to put there instead of the actual body of the message. If the Header element is present, it must be the first child element of the Envelope element.
