WebService发送请求初始化异常，求助指点迷津

Question

艺龙的酒店预订功能，SOAP使用XML消息调用远程Login方法。
当执行到Dispatch.invoke时候就报初始化错误。请各位帮忙看下，谢谢！错误信息：

System.out.println(payload);

} catch (IOException e) {

} catch (JAXBException e) {
e.printStackTrace();
}@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "LoginRequest", propOrder = {
    "userName",
    "password"
})
public class LoginRequest
    extends Request
{    @XmlElement(name = "UserName")
    protected String userName;
    @XmlElement(name = "Password")
    protected String password;
}
程序生成xml内容:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<Login xmlns="http://elong.com/NorthBoundAPI/">
<loginRequest>
<UserName>aaa</UserName>
<Password>aaa</Password>
</loginRequest>
</Login>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>艺龙本身示例xml内容:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <Login xmlns="http://elong.com/NorthBoundAPI/">
      <loginRequest>
        <RequestHead>
          <LoginToken />
          <Language />
          <GUID />
          <Version />
          <TestMode>0</TestMode>
        </RequestHead>
        <UserName>aaa</UserName>
        <Password>aaa</Password>
      </loginRequest>
    </Login>
  </soap:Body>

com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to com.sun.xml.internal.bind.api.JAXBRIContextjar包错了吧。
