SOAP Protocol

SOAP (Simple Object Access Protocol) is a protocol for exchanging structured information among Web Services. It relies on XML for its message format.

Protocol name in port definition: soap.


SOAP Transport

To adhere to the WSDL specification, simple call signatures like test( string )( int ) should be omitted. Input and output values should be passed by apposite compound structures with a void root value, as shown here.


SOAP Parameters

     * Media Type.
     * Jolie allows to set the parameter to "gzip" or "deflate" which overrides
     * also the "Accept-Encoding" header. This invites the server to use the same
     * algorithm for the response compression. Invalid values are ignored.
     * If all conditions are met, the request content gets compressed, an
     * additional "Content-Encoding" header added and the "Content-Length"
     * header recalculated.
