java-ee - Java EE EJB部署错误：容器已注册

我在我的本地计算机上运行JBoss 5服务器，我需要从我的Java EE项目到postgresql数据库有一个可用的数据库连接。我开发了一个名为UserManager的java类，其代码为：

import javax.ejb.Local;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;


@Stateless(name="UserManager1")
@Local(UserManagerItf.class)
public class UserManager implements UserManagerItf {

    @PersistenceContext
    private EntityManager em;

    public boolean addUser(Joueur j) {
        Joueur jexist = em.find(Joueur.class, j.getLogin());
        if(jexist==null) {
            em.persist(j);
            return true;
        } else {
            return false;
        }

    }

}

问题是，在我使用eclipse导出我的.war文件后，我在部署中使用我的.war文件运行jboss，我得到了这个部署错误：


18:47:27,645 INFO  [BeanInstantiatorDeployerBase] Installed org.jboss.ejb3.instantiator.impl.Ejb31SpecBeanInstantiator@57b08b4f into MC at org.jboss.ejb.bean.instantiator/JEE/JEE/UserManager1
