如何使用JAX-WS WS故障

Question

我已经写了一个webservice，并试图抛出我的自定义异常，但我得到错误，请帮助我解决它。

import javax.jws.WebService;
import javax.xml.ws.Endpoint;

@WebService(name = "WebService")
public class WebServiceTest {
    public String sayHello(String name) throws InvalidInputException {
        throw new InvalidInputException("I am testing", null);
    }
    public static void main(String[] args) {
        WebServiceTest server = new WebServiceTest();
        Endpoint endpoint = Endpoint.publish(
                "http://localhost:9191/webServiceTest", server);
    }
}


import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;

@XmlType(name = "InputMessageValidationFaultType")
public class FaultBean {

    @XmlAttribute
    protected String msg;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String value) {
        this.msg = value;
    }

}


import javax.xml.ws.WebFault;

@WebFault(faultBean = "mytest.com.inc.FaultBean")
public class InvalidInputException extends Exception {

    private static final long serialVersionUID = 1L;

    private FaultBean faultBean;

    public InvalidInputException() {
        super();
    }

    public InvalidInputException(String message, FaultBean faultBean,
            Throwable cause) {
        super(message, cause);
        this.faultBean = faultBean;
    }

    public InvalidInputException(String message, FaultBean faultBean) {
        super(message);
        this.faultBean = faultBean;
    }

    public FaultBean getFaultInfo() {
        return faultBean;
    }
}

我知道以前的问题，但我认为FaultBean类中的方法名必须是getMessage和setMessage (相对于getMsg和setMsg) --参见这篇优秀的文章：

上一次我看到这个错误时，是由于JAX使用的版本(2.1.x和2.2.x)不匹配造成的，您可能是针对2.1.x版本编译的，但运行的是2.2.x，或者是相反的版本。

请记住，JDK 6包含JAX-WS的2.1.x版本，因此您可能必须使用经过认可的库机制来强制使用2.2.x
