A JAX-WS web service essentially consists of a Java class annotated with the javax.jws.WebService annotation—the web service endpoint. A web service may optionally consist of a Service Endpoint Interface (SEI) that is implemented by the service endpoint implementation class. A web service implementation class must not be abstract or final. Business methods of the implementation class that are to be exposed as operations to a web service client must be public, must not be static or final, and must be annotated with the @WebMethod annotation.
