如何解決這個「找不到查詢類的持久類」消息？

我正在使用zkoss 5.0.4，Spring 3.0.3，Hibernate 3和JpA 1.0以及JBOSS 5.1 GA（支持JDK）創建Web應用程序。如何解決這個「找不到查詢類的持久類」消息？

該項目與JBOSS編譯良好。但是，看起來，這種依賴並不是因爲某種原因而適用的。

當我運行在控制檯應用程序，它會顯示以下內容：

10:07:35,265 WARN [QuerySplitter] no persistent classes found for query class: from org.zkforge.zktodo2.Reminder

我在我的持久性文件中添加了以下內容，並且它開始正常。

<class>org.zkforge.zktodo2.Reminder</class >

添加上面的行在數據庫中創建了表，並且持久性錯誤消失了。

我不知道爲什麼我們需要添加它。有什麼理由嗎？ Spring或Hibernate不應該從Reminder.java文件中獲得這個東西嗎？

日誌文件有以下幾點：

10:06:41,375 WARN [Ejb3Configuration] Persistence 
提供商調用者不執行 EJB3規範正確。 PersistenceUnitInfo.getNewTempClassLoader（）爲空。 10：06：41515 INFO [AnnotationBinder]從註解類綁定實體： org.zkforge.zktodo2.Reminder

我想你應該在提醒類重新審視。

你好拉古拉姆，我沒有得到你到底。但提醒課對我來說似乎沒問題。 – amar4kintu 2010-10-02 06:32:42

對我來說，這是錯誤的sessionFactory配置packagesToScan這是造成問題的原因

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 

    .... 
<!-- package was incorrect here --> 
<property name="packagesToScan" value="com.foo.test.bean"/>
