Initialization of bean failed; nested exception is org.springframework.beans

Question

I Keep my model class in the com.anand.model.Employee.java and correctly I mentioned in the sdnext-servlet.xml for annotatedClasses. But still I am getting the error. Please help me to solve this issue.

sdnext-servlet.xml

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>com.anand.model.Employee</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>             
            </props>
        </property>
    </bean>

Answer 1

This is an alternative to what you have done. Try to replace the annotatedClasses with that of the following element in your config and clean build your workspace after that + restart your server .

<property name="packagesToScan">
    <list>
        <value>com.anand.model</value>           
    </list>
</property>
