在java中創建非常簡單的Web服務時運行時建模器錯誤

Question

我是java網絡服務的初學者。

我創建了一個簡單的Web服務，並在嘗試發布時如下所示

 Endpoint.publish("http://localhost:8080/HelloWeb", new HelloWeb());

獲得如下錯誤

Exception in thread "main" com.sun.xml.internal.ws.model.RuntimeModelerException: runtime modeler error: Wrapper class com.ravi.jaxws.SayGreeting is not found. Have you run APT to generate them?

任何想法在這里出錯了。

我的webservice類非常簡單，這里是代碼：

    @WebService
@SOAPBinding(style = Style.DOCUMENT, use=Use.LITERAL)
public class HelloWeb {

    @WebMethod
    public String sayHello(String name){
        return "Hello "+name;
    }
}

首先調用wsgen實用程序。 此實用程序生成各種工件，即Endpoint.publish方法生成服務的WSDL所需的java類型.Here是示例在工作目錄中運行

  wsgen -keep -cp  package.HelloWeb
