    }

    @Override

        // TODO Auto-generated method stub

    }

}

This is my Dispatcher Servlet (HelloWeb-servlet.xml)

When I try to run the project, I am getting the following error

Error creating bean with name 'task_impl_bean': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.hibernate.SessionFactory org.mod.Prime.DAO.Implementation.Task_Impl.sessionfactory; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionfactory' defined in ServletContext resource [/WEB-INF/HelloWeb-servlet.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/util/DTDEntityResolver

The main root cause is

Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/util/DTDEntityResolver

As you can see in my pom file I have included the hibernate jars. I dont know whats the exact error. Could someone help me? Thanks in advance

Answer 1

Try to declare the dataSourceBean before the sessionFactory

<bean id="dataSourceBean" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.postgresql.Driver"/>
    <property name="url" value="jdbc:postgresql://localhost:5432/newdatabase"/>
    <property name="username" value="postgres"/>
    <property name="password" value="P@ssword"/>
</bean>

<bean id="sessionfactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSourceBean"></property>
    <property name="annotatedClasses" value="org.mod.Prime.Data.Task"></property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
        </props>
    </property>
</bean>

Answer 2

This is dynamic class loading while Bean init! DTD entity Resolver is used while parsing the Spring Bean class while loading into the container. I think the version of your Hibernate is not compatible with your framework and code! Why are you using different hibernate-annotations version?

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-annotations</artifactId>
            <version>3.5.6-Final</version>
        </dependency>

Are you sure that your Hibernate version is compatible with your Spring framework? Try to change the versions, also check your JVM version you are using to run the Spring server!
