Question

I am trying to learn how to use DAO and BO classes and I am getting the following error

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [spring/database/Hibernate.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'annotatedClasses' of bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Bean property 'annotatedClasses' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

Hibernate.xml

            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean> 

I dont know where the error is coming from as my getter and setter methods in my countries.java and customer.java classes are all correct!

Does anybody know whats going wrong? (if you need to see any of the other classes just add a comment saying which classes and il post them up)

Thanks

Answer 1

It’s actually complaining about the annotatedClasses property of the session factory, you are using a LocalSessionFactoryBean that doesn’t have it (you have commented out AnnotationSessionFactoryBean that does have it).
