javax.xml.ws.WebServiceException：没有可用的地址

Question

我有一个有状态的WebService和一个无状态的WebService，它将EndPointReference返回给有状态Web服务的新实例。与此博客https://weblogs.java.net/blog/kohsuke/archive/2006/10/stateful_web_se.html

中的示例一样

@Stateful
@WebService
@Addressing
class BankAccount {
protected final int id;
private int balance;

public BankAccount(int id) { this.id = id; }

@WebMethod
public void deposit(int amount) { balance+=amount; }

// either via a public static field

public static StatefulWebServiceManager<BankAccount> manager;
}

...

@WebService
class Bank { // this is ordinary stateless service
    @WebMethod
    public synchronized W3CEndpointReference login(int accountId) {
          BankAccount acc = new BankAccount(accountId);
          return BankAccount.manager.export(acc);
    }
}

但是当我运行客户端并调用无状态服务方法“login”时，我得到以下异常：

javax.xml.ws.WebServiceException: No address is available for {http://server.stateful
/}BankAccountPort

我做错了什么？
