Spring 2.5 是不是和 Spring2.0 不兼容啊?

原先配置的事务处理现在都不可用了，总是抛出hibernate异常：

javax.servlet.ServletException: org.hibernate.HibernateException: createQuery is not valid without active transaction
	org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:515)
	org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:419)

我的配置如下：
hibernate.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="configLocation" value="classpath:hibernate.cfg.xml" />
	</bean>
</beans>
