Hi, I try to convert my current running application, which uses xml configuration file for hibernate mapping to annotation. I only do so partially for 1 class right now. However, I run into no class def found. This class is verified to be inside the hibernate.jar.

Could someone please glance down below to see where the problem maybe? Thanks.

Hibernate version:
3.2.6.ga

Annotation version: 3.3.0.GA

Mapping documents:
hibernate.cfg.xml
Code:
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
   <session-factory>
      <mapping class="com.someclass"/>
   </session-factory>
</hibernate-configuration>



beans-db.xml
Code:
<bean id="sessionFactory"
      class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
      autowire="byName">
      <property name="hibernateProperties">
         <props>
            <prop key="hibernate.dialect">
               org.hibernate.dialect.Oracle9Dialect
            </prop>
                                <prop key="hibernate.hbm2ddl.auto">validate</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.use_sql_comments">true</prop>
            <prop key="hibernate.cache.provider_class">
               org.hibernate.cache.EhCacheProvider
            </prop>
            <prop key="hibernate.cache.use_query_cache">true</prop>
            <prop key="net.sf.ehcache.configurationResourceName">/ehcache.xml</prop>
         </props>
      </property>
               <property  name="configurationClass">
                   <value>org.hibernate.cfg.AnnotationConfiguration</value>
               </property>
               <property name="configLocation">
                   <value>/hibernate.cfg.xml</value>
               </property>
      <property name="mappingResources">
      <list>
                       <value>/somefile.hbm.xml</value>
      </property>
   </bean>

This is a class loading issue. Delete extra hibernate jar files and you should be good.

Do you mean I only need the library hibernate-annotations.jar, but not hibernate.jar? When I remove that, I get some error such as the following not found:

org.hibernate.usertype.UserType
org.hibernate.HibernateException

Unless you mean I have two hibernate.jar in my library path. I didn't see that in my project's library path, but I can look deeper if that's the case. Thanks.

That's what I meant. You have multiple hibernate.jar files on your classpath.

Thank you very much. I found another hibernate.jar in the deployment domain's lib.
