NamedQuery未找到Hibernate4煤層2.2 JPA 2.0和JBoss EAP 6

我收到JBOSS EAP 6.3服務器上的命名查詢未發現錯誤消息。我在我的應用程序中使用Hibernate4 Seam 2.2 JPA 2.0和Jboss eap 6。NamedQuery未找到Hibernate4煤層2.2 JPA 2.0和JBoss EAP 6

我的實體類，

@Entity 
@Table(name="OFFICER") 
@NamedQueries({ 
@NamedQuery(name="findOfficerByEmployeeId", 
      query="from Officer where upper(employeeId)=upper(:id) order by employeeId"), 
@NamedQuery(name="findOfficerByEmpIDFetchAssigners", 
      query="from Officer o left join fetch o.assigners ass where upper(o.employeeId) = :id")  
}) 
public class Officer implements java.io.Serializable {

，這裏是我的無狀態bean類我打電話了NamedQuery，

@Stateless 
@Name("batchProcessor") 
@AutoCreate 
@TransactionManagement(TransactionManagementType.BEAN) 
public class BatchProcessorBean implements BatchProcessor, Serializable { 
private static final long serialVersionUID = 395715959808111918L; 

@SuppressWarnings("seam-unresolved-variable") 
@In(value = "entityManager") 
private EntityManager em; 

public Officer getLoggedInUser(String employeeID) { 
    UserTransaction instance = Transaction.instance(); 
    List<Officer> list = em.createNamedQuery("findOfficerByEmpIDFetchAssigners").setParameter("id", employeeID).getResultList();

我放置persistence.xml中在下EJB /資源/ META-INF文件夾。 我已經嘗試了關於NamedQuery未找到問題的以前的帖子。那不是我修的問題

請幫我找出這個問題。由於

我已經解決了這個問題。我已經添加了下面的類標籤persistence.xml中解決這個問題，

<class>com.wachovia.apps.amaster.orm.Officer</class>

標記的順序是在persistence.xml中很重要的。在我而言，這個類標籤必須在<properties>標記之前和<jta-data-source>標籤後加入。
