Can a WSDL indicate the SOAP version (1.1 or 1.2) of the web service?

Is it possible to see if a web service uses SOAP 1.1 or 1.2, based on the information in the WSDL?

Solution

  • SOAP 1.1 uses namespace http://schemas.xmlsoap.org/wsdl/soap/

    SOAP 1.2 uses namespace http://schemas.xmlsoap.org/wsdl/soap12/

    The wsdl is able to define operations under soap 1.1 and soap 1.2 at the same time in the same wsdl. Thats useful if you need to evolve your wsdl to support new functionality that requires soap 1.2 (eg. MTOM), in this case you dont need to create a new service but just evolve the original one.
