服务端代码:
package voluntee.Attendance.System.EJ;

public class DataVolunteeAttendanceSystemEJ {
 private int memberId;

 public int getMemberId() {
  return memberId;
 }

 public void setMemberId(int memberId) {
  this.memberId = memberId;
 }
}

....................................................................................................................
我想把memberId 值变成12345  然后在荧幕打印出来, 客户端代码要怎麼写?
(最好给个完整的)

有人建议我这样:
public static void main(String[] args) {  
    DataVolunteeAttendanceSystemEJ dvas = new DataVolunteeAttendanceSystemEJ();  
dvas.setMemberId(12345);  
    System.out.println(dvas.getMemberId());  
}


不过有报错，eclipse建议我改成
DataVolunteeAttendanceSystemEJStub dvas = new DataVolunteeAttendanceSystemEJStub();

改完后dvas.setMemberId(12345);也报错了

我客户端有2个class
DataVolunteeAttendanceSystemEJCallbackHandler
和
DataVolunteeAttendanceSystemEJStub
不知有什么用?
有人给点意见吗?
