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

<context:annotation-config />

<context:component-scan base-package="com.eport" />

    <context:property-placeholder location="classpath:jdbc.properties" />

这是hibernate配置文件

<mapping class="com.eport.account.pojo.SystemPrivilege"/>
    </session-factory>

这是dao配置文件

private String methodOrderby(LinkedHashMap<String, String> orderby) {

for (String key : orderby.keySet()) {
sb.append("o.").append(key).append(" ").append(orderby.get(key)).append(",");
}
sb.deleteCharAt(sb.length() - 1);// 删除最后多余的逗号
}
return sb.toString();
}

/**

* @param params
*/

}
}

/**

}
return name;
}

protected static <E> String getCountField(Class<E> clazz) {
String out = "o";
try {
PropertyDescriptor[] propertyDescriptors = Introspector.getBeanInfo(clazz).getPropertyDescriptors();
for (PropertyDescriptor propertydesc : propertyDescriptors) {
Method method = propertydesc.getReadMethod();
if (method != null && method.isAnnotationPresent(EmbeddedId.class)) {
PropertyDescriptor[] ps = Introspector.getBeanInfo(propertydesc.getPropertyType())
.getPropertyDescriptors();
out = "o." + propertydesc.getName() + "."
+ (!ps[1].getName().equals("class") ? ps[1].getName() : ps[0].getName());
break;
}
}
} catch (Exception e) {
e.printStackTrace();
}
return out;
}

}
但是我在运行的时候报了错误
java.lang.ClassCastException: org.springframework.orm.hibernate4.SessionHolder cannot be cast to org.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
