Local and Remote Interfaces cannot have duplicate interface for bean UserManagerBean错误

解决：http://www.blogjava.net/Bobbyliao/archive/2008/10/01/232018.html

  后来发现，原来是UserManagerBean中的@Local,@Remote必须明确写上接口的类型，才可以。修改代码如下：

package cn.study.ejb;

import javax.ejb.Local;
import javax.ejb.Remote;
import javax.ejb.Stateless;

@Stateless
@Remote(UserManager.class)
@Local(UserManager.class)
public class UserManagerBean implements UserManager {

public void addUser(User user) {
        System.out.println(user.getUsername() + "已经被成功保存！");
        user.setId(13);
    }

}
