have defined a Java Interface with the annotation @WebService Compiled the code which went fine
Example:
@WebService
public interface H
The JAX-WS Specification makes this cleas in section 3.3, page 30:
You can use the endpointInterface
attribute to separate between the implementing class and the interface. Basically, this determines what will be mapped to your wsdl:portType
when you deploy the service and the wsdl:definition
is generated.
If you do not define the endpointInterface
all public methods of the annotated class will be mapped to wsdl:operation
(as long as you do not influence this behaviour with @WebMethod
annotations).
If you do define the endpointInterface
, it has to point to some type which the annotated class implements (or, well, itself as demonstrated in your question). Then, the public methods of this type are used for mapping the wsdl:portType
, instead of the methods of the annotated class.
To sum up: The definition of endpointInterface
only makes sense if you use the @WebService
on an implementing class and want your WSDL to be generated based on the interface it implements. In your current setting where you use the annotation on the interface com.ws.HelloWorldIfc
, there really isn't any difference. So you lose nothing by just skipping it. The annotation is useful if you want your implementation class to provide public methods that should not go into the generated WSDL.
