JaxwsHandler Configuration

Table 10.1. JaxwsHandler constructor parameters

implementorThe web service instance. When using programmatic approach, it might be just an instance of class, annotated as @WebService. By using "implementor" approach, when constructing JaxwsHandler, we're actually asking JAX-WS core to configure web service basing on implementor's class name and annotations.
endpointThe web services, represented by WSEndpoint. Unlike "implementor" approach, when using endpoint, we can customize web service more finely. It's also possible to use external config files in this case.
isAsyncIf true, the JaxwsHandler will execute WebService in asynchronous mode, otherwise synchronous.
