When you use the AddressingFeature class to acquire SEI, the JAX-WS engine of the Web Service client machine sets up an anonymous URI in the wsa:ReplyTo/wsa:Address element of the addressing header. At this time, if you invoke the following Web Service, the anonymous URI cannot be used, so WebServiceException occurs when invoking a service method:

• a Web Service wherein prohibited is specified in the wsa:Anonymous element of a WSDL
• a Web Service wherein the wsam:NonAnonymousResponses element is specified in the child element of the wsam:Addressing element

To communicate with a Web Service wherein prohibited is specified in the wsa:Anonymous element or the wsam:NonAnonymousResponses element is specified in the child element of the wsam:Addressing element, create an addressing header specifying a non-anonymous URI.
