Question

Estoy tratando de migrar para hibernar 4.1.0.Final con el resorte 3.1.1.RELEASE y la siguiente es mi configuración para hibernar:

 <property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="${project.groupId}.domain" />
<!-- control the behavior of Hibernate at runtime,All are optional and
have reasonable default values -->
<property name="hibernateProperties">
<value>
<!-- hibernate.dialect: allows Hibernate to generate SQL optimized for
a particular relational database -->
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.hbm2ddl.auto=create-drop
hibernate.show_sql=false
hibernate.jdbc.fetch_size=100
hibernate.jdbc.batch_size=100
hibernate.jdbc.batch_versioned_data=true
hibernate.order_inserts=true
hibernate.order_updates=true
hibernate.cache.use_query_cache=false
hibernate.cache.use_second_level_cache=false
</value>
</property>
</bean>
<!-- provides properties to hibernate to make it able to create session
factory. Hibernate uses instance of session bean of type -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="${db.url}" />
<property name="username" value="${db.username}" />
<property name="password" value="${db.password}" />
</bean>
<!-- responsible for creating sessionFactory opening transactions and binding
them to the current thread context. -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
<property name="nestedTransactionAllowed" value="true" />
</bean>
<!-- get exception translation from HibernateException into DataAccessException
hierarchy -->
<bean
class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />

pero al intentar ejecutar la aplicación, obtuve la siguiente excepción:

 java.lang.ClassNotFoundException: org.hibernate.engine.SessionFactoryImplementor
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1678)
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1523)

por favor, avíseme por qué me aparece este error y cómo solucionarlo, gracias.

Intenta usar org.springframework.orm.hibernate4.HibernateTransactionManager

 <bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="dataSource" ref="dataSource" />
<property name="sessionFactory" ref="sessionFactory" />
</bean>
