Hibernate4 integrated spring3.1 the nested exception is java. lang. NoClassDefFoundError: org/hibernate/engine/Sess

Error message: org. springframework. beans. factory. BeanCreationException: Error creating bean with name 'userservice' defined in file [F: \ eclipse \ ec_wp \ SpringProgramming0300

[Beans. xml]: Invocation of init method failed; nested exception is Java. lang. NoClassDefFoundError: org/hibernate/engine/SessionFactoryImplementor

There is still a difference between hibernate4 and hibernate3.

Original: (hibernate3)

<bean id="transactionManager"    class="org.springframework.orm.hibernate3.HibernateTransactionManager">    <property name="sessionFactory" ref="sessionFactory" />    <property name="nestedTransactionAllowed" value="true" /></bean>

Now (Hibernate4)

//Try using the 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>

The problem is solved.
