请问 我这个要怎么做测试啊，总是报错..
Error creating bean with name 'datasource' defined in class path resource [bean-pub.xml]:
bean-pub.xml 为:
<!--JNDI 配置DataSource -->
<bean id="datasource"
    class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName">
        <value>java:comp/env/jdbc/crm</value>
    </property>
</bean>
   

<!--定义 SessionFactory -->
<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="datasource"/>
