eclipse - 如何修复 "Trying to write END_DOCUMENT when document has no root"错误？

Question

我将继续 =)) 使用 Eclipse 在 Tomcat 7 上创建 jax-ws soap Web 服务(取得了不同程度的成功)。

我的 Eclipse“mavened”webapp 项目中有接口(interface):

@WebService(targetNamespace = "http://new.webservice.namespace", name = "MayaServiceInterface")
@XmlSeeAlso({ObjectFactory.class})
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
public interface MayaServiceInterface {


    @WebResult(name = "getPersonResponse", targetNamespace = "http://new.webservice.namespace", partName = "parameter")
    public getPersonResponse getCustomer(
        @WebParam(partName = "parameter", name = "getPersonRequest", targetNamespace = "http://new.webservice.namespace")
        getPersonRequest parameter

    );

}

和实现接口(interface)的类:

@javax.jws.WebService
     (
                      serviceName = "ABCWsService",
                      portName = "ABCWsPort",
                      targetNamespace = "http://new.webservice.namespace",
                      endpointInterface = "com.mayacomp.ws.MayaServiceInterface")


public class MayaServiceEndPoindImpl implements MayaServiceInterface {

    @Override
    public getPersonResponse getCustomer(getPersonRequest parameter) {
        // TODO Auto-generated method stub
        return null;
    }


} // end of class

当我尝试“在服务器上运行”网络服务时，我收到一个包含下一个信息的页面:

Web Services Endpoint Information Service Name: {http://new.webservice.namespace}ABCWsService Port Name: {http://new.webservice.namespace}ABCWsPort Address: http://localhost:8080/maya-web-service/ABCWs WSDL: http://localhost:8080/maya-web-service/ABCWs?wsdl Implementation class: com.mayacomp.ws.MayaServiceEndPoindImpl

当我点击 http://localhost:8080/maya-web-service/ABCWs?wsdl 时我在 Eclipse 控制台中收到 HTTP 500 错误和下一个信息:

但我正在等待接收 wsdl(如果这听起来不奇怪的话)。请帮助我修复此错误并查看我的 wsdl。

问题是关于 stax-ex jar。

• 您可以将 stax-ex-1.7.7.jar 放到您的库位置
• 你可以添加 org.jvnet.staxex 网站 斯塔克斯 1.7.7

到你的 pom.xml
