大家帮我看个项目的目录结构，我不知道这是一个什么项目。

老师给我这个源码，要我去看，
ps：给我的时候我记得很清楚的一句是：你学的hibernate要映射文件。现在的都不用了。

大家看看，给我弄个头绪出来，这里到底有哪些货色啊，
只给我一周时间消化。

项目的整体结构是

[img]/upload/attachment/92994/04f800d9-df2b-3779-ad3f-0f751f3bafae.bmp[/img]

具体如下：

[img]/upload/attachment/92996/d5de118b-c640-3ec2-b641-937a6d6e9ad6.bmp[/img]

谢谢了。

[b]问题补充：[/b]
谢谢你们了，大致就是这样几个东西。那个jpa具体是哪方面东东啊

好像是，基于Spring、Struts2、TopLink框架及ExtJs框架设计的一个简单Web开发应用框架

FreeMaker + Ext + Spring + JPA ?

FreeMaker + ExtJS + Struts2 + Spring + JPA ?

　　Java Persistence API
　　JPA通过JDK 5.0注解或XML描述对象－关系表的映射关系，并将运行期的实体对象持久化到数据库中。
