ssh整合问题
我前面整合的spring3+struts2+hibernate4.由于要使用jbpm4，所以hibernate要换成3.
这是spring配置文件
<!--开启注解处理器-->
<context:annotation-config/>
<!--扫描包路径-->
<context:component-scanbase-package="com.eport"/>
<!--加载jdbc.properties文件-->
<context:property-placeholderlocation="classpath:jdbc.properties"/>
<!--配置数据源-->

<!--整合hibernate-->

这是hibernate配置文件

<mappingclass="com.eport.account.pojo.PrivilegeGroup"/>
<mappingclass="com.eport.account.pojo.SystemPrivilege"/>
</session-factory>
</hibernate-configuration>
这是dao配置文件

但是我在运行的时候报了错误
java.lang.ClassCastException:org.springframework.orm.hibernate4.SessionHoldercannotbecasttoorg.springframework.orm.hibernate3.SessionHolder
hibernate4.SessionHolder不能转换为hibernate3.SessionHolder。但是我都改成hibernate3
了啊。不知道这个hibernate4是哪里来的
