java - ejb中的Web服务问题

Question

我的网络服务方法中有一个我无法理解的错误。

首先，方法如下:

package com.ubb.damate.webservice;

import java.util.Date;

import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.jws.WebParam;
import javax.jws.WebService;

import com.ubb.damate.model.UserEvent;
import com.ubb.damate.model.UserEventPK;
import com.ubb.damate.service.UserEventServiceLocal;
import com.ubb.damate.util.DateUtils;

/** Session Bean implementation class UserEventWebService */
@Stateless
@WebService
public class UserEventWebService {
@EJB(beanName = "UserEventService")
private UserEventServiceLocal   userEventService;

public String createOrUpdate(@WebParam(name = "Eventvalue") String eventvalue, @WebParam(name = "Username") String username, @WebParam(name = "Eventname") String eventname) {
    Date date = DateUtils.createDate(-1, 1, 1);

    UserEventPK userPk = new UserEventPK();
    userPk.setEventname(eventname);
    userPk.setUsername(username);
    userPk.setEventdate(date);

    UserEvent userEvent = new UserEvent();
    userEvent.setId(userPk);

    String a = userEvent.getEventvalue();

    userEvent = userEventService.find(userEvent);

    String b = userEvent.getEventvalue();

    //userEvent.setEventvalue(eventvalue);

    userEventService.createOrUpdate(userEvent);

    return "\"" + a + "\" - \"" + b + "\"";
}
}

现在这是错误消息:

添加了整个 Webservice 类。

Answer 1

我找到了答案。一个包中的 2 个 webmethods 不能具有相似的名称。
