Java – the response of a web service using Apache CXF displays “unbound operation information..”
•
Java
The problem description may be long Please be patient and provide any help, because I am a new network service
What I did: I created a web service in Java using Apache CXF RI I just created a class and used the bottom-up development method to generate SEI, WSDL and XML files
The problem is: now, if I request "http: / / localhost: 8084 / deepthoughtws / services / deepthoughtport / whatistheanswer", unbound operation information will be output when calling the unknown method The reply is as follows:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>No binding operation info while invoking unkNown
method with params unkNown.</faultstring>
</soap:Fault>
</soap:Body>
</soap:Envelope>
The generated WSDL is:
<wsdl:deFinitions xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

Deepthought courses include:
@WebService(targetNamespace = "http://ws.service.com/",portName = "DeepThoughtPort",serviceName = "DeepThoughtService")
public class DeepThought {
public String whatIsTheAnswer(@WebParam(name = "arg0") String interviewer) {
return ("The answer " + interviewer);
}
}
The console output at the time of the request also shows some errors:

Solution
Source of the above explanation.
Possible solutions:
@WebService(targetNamespace = "http://ws.service.com/",serviceName = "DeepThoughtService",endpointInterface = "your.pck.DeepThoughtService",wsdlLocation = "WEB-INF/wsdl/DeepThoughtService.wsdl")
public class DeepThought {
@WebMethod(action = "whatIsTheAnswer")
public String whatIsTheAnswer(@WebParam(name = "arg0") String interviewer) {
return ("The answer " + interviewer);
}
}
What I'm going to do is add the WSDL location and endpointinterface to your @ WebService In addition, you use Java first method, so your method should be annotated with @ webmethod (action = "whatistheanswer") So if the method has no annotation, CXF "understands" that your web service does not contain any methods at all, and says: there is no binding operation information, but the calling of unknown methods and params are unknown
