WSDL - One way operations

[Anjali S Sharma]

I am trying to create a webservice using Axis2 which has a method with no parameter. This method does not accept a parameter but returns a value.

Please refer to "getAllResumeIds" operation. The below WSDL gives me a warning

"WS-I: (BP2208) wsdl:operation was not a request/response or one-way operation". 

Also the code generation from this WSDL fails.

Can someone please let me know how to resolve this?

Thank you

Anjali,

If your service operation has no input parameter and just return then the message exchange pattern still has to be request-response for your output-only operation.

  <wsdl:operation name="getAllResumeIds">            
                     <wsdl:output message="tns:getResumeIdsResponse"></wsdl:output>   
           </wsdl:operation>    

You need to have a wsdl:input for this but the message you point towards has just the name and no message part, ie

  <message name="getEmpty"></message>

Thanks a lot.
