    copied!<p>The session factory I have defined is null in DAO. Here goes my code:</p> <pre><code>@Repository public class LinkDetailsDAO { private SessionFactory sessionFactory; @Autowired public void setSessionFactory(SessionFactory sessionFactory) { this.sessionFactory = sessionFactory; } Session session = sessionFactory.getCurrentSession(); </code></pre> <p>throws an null pointer when i am trying to create a session object.</p> <p>My applicationContext:</p> <pre><code> &lt;!-- Load Hibernate related configuration --&gt; &lt;import resource="hibernate-context.xml"/&gt; &lt;context:annotation-config/&gt; &lt;context:component-scan base-package="com.Neuverd.*"/&gt; </code></pre> <p>My hibernate-context:</p> <pre><code> &lt;context:property-placeholder location="/WEB-INF/config/testapp.properties" /&gt; &lt;!-- Enable annotation style of managing transactions --&gt; &lt;tx:annotation-driven transaction-manager="transactionManager" /&gt; &lt;!-- Declare the Hibernate SessionFactory for retrieving Hibernate sessions --&gt; &lt;bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" p:dataSource-ref="dataSource" p:configLocation="/WEB-INF/config/hibernate.cfg.xml" p:packagesToScan="com.Neuverd"/&gt; &lt;!-- Declare a datasource that has pooling capabilities--&gt; &lt;bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" p:driverClassName="${app.jdbc.driverClassName}" p:url="${app.jdbc.url}" p:username="${app.jdbc.username}" p:password="${app.jdbc.password}" /&gt; </code></pre> <p> </p> <p>and my hibernate config file</p> <pre><code>&lt;hibernate-configuration&gt; &lt;session-factory&gt; &lt;!-- We're using MySQL database so the dialect needs to MySQL as well--&gt; &lt;property name="hibernate.dialect"&gt;org.hibernate.dialect.MySQL5InnoDBDialect&lt;/property&gt; &lt;!-- Enable this to see the SQL statements in the logs--&gt; &lt;property name="show_sql"&gt;true&lt;/property&gt; &lt;property name="hbm2ddl.auto"&gt;create&lt;/property&gt; &lt;/session-factory&gt; &lt;/hibernate-configuration&gt; </code></pre> <p>I have tried using the @Resource annotation too. but no luck. I am using Spring 3.1 and Hibernate 4.1.</p> <p>Application throws a beancreationexception for LinkDetailsDAO during start up, caused due to the above mentioned nullpointer.</p> <p>After the sessionfactory bean and transactionManager bean is created, when the container tries to create the LinkDetailsDAO bean, it fails. I don't understand why a null sessionfactory bean is created!!. Tried a sessionfactory as mentioned in the <a href="http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/orm.html#orm-session-factory-setup" rel="nofollow">spring</a> doc. Not working.</p>
