调用JAX-WS服务方法时出错

我在调用JAX-WS服务方法时遇到问题。我的服务似乎成功部署。

界面如下：

@WebService(targetNamespace = "http://bioflip.org/wsdl")
public interface IUserService { //@WebMethod stubs go here }

，实现如下：

@Stateless
@WebService(
        portName = "UserPort",
        serviceName = "UserService",
        targetNamespace = "http://bioflip.org/wsdl",
        endpointInterface = "IUserService")
public class UserService implements IUserService
{
 //@Override implementations of the interface web methods go here.
}

以下是运行服务时产生的WSDL标题：

<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://bioflip.org/wsdl" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" name="UserService" targetNamespace="http://bioflip.org/wsdl">
<wsdl:types>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://bioflip.org/wsdl" elementFormDefault="unqualified" targetNamespace="http://bioflip.org/wsdl" version="1.0">

可以在以下地址找到WSDL：

http://localhost:8080/BioFlipService/webservices/UserService?wsdl

如果我只是访问：

http://localhost:8080/BioFlipService/webservices/UserService

我收到消息：

  

此XML文件似乎没有任何关联的样式信息   用它。文档树如下所示。

我认为没问题。但是，当尝试从我的客户端访问服务时，如下所示：

IUserService userServiceClient;
Service userService = Service.create(
        new URL("http://localhost:8080/BioFlipService/webservices/UserService?wsdl"),
        new QName("http://bioflip.org/wsdl","UserService"));
userServiceClient = userService.getPort(IUserService.class);

boolean enrolled1 = userServiceClient.enrollUser(zach);

我得到以下错误客户端：

我做错了什么？

1 个答案:

答案 0 :(得分：0)

嗯..呃..我对jax-ws一无所知，但最后一点是“NoSuchMethodError”，意味着JVM无法找到构造函数BioFlip.User .. 该类是否已成功部署到服务器？它与您用于编译BioFlip.UserFactory的版本相同吗？

基本上，如果你编译两个java文件，那么你改变/编译一个，这样就不会发生另一个这种情况。
