WSDL error when retrieving WSDL definition of an Axis service

[Ravi]

http://localhost:8080/axis/services/urn:EchoAttachmentsService?wsdl I got the same error !!! Namespace prefixes must be set on the Definition object using the addNamespace(...) echoAttachment service work fine. Thank for help. I need a correct WSDL definition to create a C++ client.   Regards, Ravi.
