org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.UnsupportedClassVersionError: Bad version number in .class file
sessionfactory的错误看到了不少的解答，但是都和我的不太一样，

applicationContext.xml内容
<beans>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect </prop>
<prop key="hibernate.show_sql">true </prop>
<prop key="hibernate.format_sql">true </prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>xml/login.hbm.xml </value>
<value>xml/Class.hbm.xml </value>
<value>xml/Student.hbm.xml </value>
</list>
</property>
</bean>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>oracle.jdbc.driver.OracleDriver </value>
</property>
<property name="url">
<value>jdbc:oracle:thin:@127.0.0.1:1521:tianfei </value>
</property>
<property name="username">
<value>scott </value>
</property>
<property name="password">
<value>tiger </value>
</property>
</bean>
</beans>

web.xml内容

用的myeclipse，tomcat一启动就报错
网友回复:是不是spring和hibernate的版本不兼容？
网友回复:Bad version
提示版本不对啊 可能不兼容吧！
网友回复:需要怎么改啊，有碰到的朋友吗，帮解答一下啊。
网友回复:在applicationContext.xml中，你的dataSource和sessionFactory在同一个文件中，所以

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" >
<property name="dataSource" >
<ref bean="dataSource"/ >

改成

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" >
<property name="dataSource" >
<ref local="dataSource"/ >

LZ看看行不？
网友回复:楼上朋友的办法不可行啊~~
我也遇上了同样的问题~~
网友回复:

呵呵....我也是这个问题啊!
正在解决中!!!
网友回复:检查一下你的LIB目录下的包有没有重复。
