If the javax.xml.ws.soap.Addressing annotation is specified in the service implementation class, the WSDL file issued by the Web Service-side JAX-WS engine and the WSDL file generated by executing the cjwsgen command become as follows:

• In the WSDL file, the wsaw:Action attribute is not only given to the wsaw:UsingAddressing element, but also to the wsdl:input element. The given value is the default Action value defined in the WS-Addressing 1.0 specifications. For details about the default Action value, reference the WS-Addressing 1.0 specifications.
• If false is specified in the required element of the javax.xml.ws.soap.Addressing annotation, the wsdl:required attribute of the wsaw:UsingAddressing element is not given in the WSDL file.
