I have been struggling with the following error the last couple of days can you please help!
I generated my server and client code using the wsdl2java tool from a ws
It happens because the source WSDL in each operation has not defined the SOAPAction value.
e.g.
His is important for axis server.
If you have created the service on netbeans or another, don't forget to set the value action on the tag @WebMethod
e.g. @WebMethod(action = "hello", operationName = "hello")
This will create the SOAPAction value by itself.
