Hibernate 4 Error on sessionFactory creation

Question

During upgrading to Hibernate 4 from its 3.v, I run into this problem occurred at the TC starting up.

... Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring/app-config.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException

And the sessionFactory in my configuration file is done as the following:

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="mappingResources">
        <list>
            <value>shippingCharge.hbm.xml</value>
        </list>
    </property>
    <property name="annotatedClasses">
        <list>
            <value>com.abc.myapp.account.domain.ProfileInfo</value>
            <value>com.abc.myapp.account.domain.Profile</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.format_sql">${hibernate.format_sql}</prop>
            <prop key="hibernate.generate_statistics">${hibernate.generate_statistics}</prop>
            <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.DefaultComponentSafeNamingStrategy
            </prop>
        </props>
    </property>
    <!--  removed for hibernate 4. any replacement?
    <property name="eventListeners">
        <map>
            <entry key="merge">
                <bean
                    class="org.springframework.orm.hibernate3.support.IdTransferringMergeEventListener" />
            </entry>
        </map>
    </property>
    -->
</bean>

How to solve this problem?

It may be foreign-key related. Maybe you could find some pointers here : stackoverflow.com/questions/9302993/… — ndeverge

Thanks for your information. In fact, I already read the post. I, however, don't think it is the same situation. This error occurs under a situation which my code hasn't been changed but Hibernate version from 3.6.8 to 4.1.0. I don't know whether the 4 version come with some special requirements on foreign key annotation configuration over the 3.6.8 version or not. — vic

The total number of domain classes are 25 which are mapped with annotations. It is not reality to show all domain classes here. The hbm file is something like the following: — vic

Please replace org.springframework.orm.hibernate4.LocalSessionFactoryBuilder instead of org.springframework.orm.hibernate4.LocalSessionFactoryBean. This might help.

it's maybe a spring issue. you can change <property name="annotatedClasses"> to <property name="packagesToScan" and try it again

this may be a stale jar file issue, i ran with the same error then in my log file i found Could not obtain connection metadata : DatabaseMetaData information is not known for server DB2/LINUXX8664SQL09010 by this version of JDBC driver
then i replaced my this project db2 jar files with one running project jars and it starts running smoothly

I was facing similar issue in my code. Then i tried updating the recent versions of DB2 jars into my server and the code started working. Try to update your DB2 jar.
