Question

The following exception is coming when I am trying to run an existing project. Any pointer will be very helpful.

Exception in thread "Thread-5" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in ServletContext resource [/WEB-INF/app_config/applicationContext-dao.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.orm.hibernate3.HibernateTransactionManager]: Constructor threw exception; nested exception is java.lang.NullPointerException

below is how the bean is defined

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
Was it helpful?

Solution

http://commons.apache.org/proper/commons-logging/apidocs/org/apache/commons/logging/LogFactory.html#getFactory()

See the link. It requires a commons-logging.properties do you have any file like that in classpath?

OTHER TIPS

İt can't find bean class and return nullpointerexception .

Check all class and package names are true and check your app'sname.hbm.xml file is true named . You have to put class name which you run in app'sname area ..

And check you mapped your app'sname.hbm.xml file into hibernate.cfg.xml file
