¿Cómo puedo solucionar este mensaje "no se encontraron clases persistentes para la clase de consulta"?

El proyecto compila bien con JBOSS. Pero parece que la persistencia no se aplica por alguna razón.

Cuando ejecuto una aplicación en la consola, se muestra lo siguiente:

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

Agregué lo siguiente en mi archivo de persistencia y comenzó bien.

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

La adición de la línea anterior creó la tabla en la base de datos, y el error de persistencia se ha ido.

No sé por qué tenemos que agregarlo. ¿Hay alguna razón? ¿No debería Spring o Hibernate obtener esa cosa del archivo Reminder.java?

archivo El registro tiene el siguiente:

Creo que debería relook en Recordatorio clase.

Hola Raghuram, no he tenido exactamente. Pero la clase de Recordatorio me parece bien. – amar4kintu

para mí fue la sessionFactory configuración incorrecta packagesToScan que estaba causando el problema

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

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