我正在做spring + hibernate apllication.当我在tomcat服务器上运行应用程序时,我遇到了一些异常.以下是我的代码.

这是我的bean配置文件.

        <property name="username" value="${jdbc.username}" />

    </bean>

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

        <property name="dataSource">

        </property> 
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
        <property name="mappingResources">
            <list>
                <value>Employee.hbm.xml</value>
            </list>
        </property>
    </bean>
    <bean id="employeeBo" class="com.saggezza.employee.bo.impl.EmployeeBoImpl">
        <property name="employeeDao" ref="employeeDao" />
    </bean>

    <bean id="employeeDao" class="com.saggezza.employee.dao.impl.EmployeeDaoImpl">
        <constructor-arg ref="sessionFactory"></constructor-arg>
    </bean>
