地址如下:

?http://czpae86.iteye.com/blog/1058754

?

项目源码见附件!!?

?

安装方法:

1,导入jar包.用到的jar包如下,请自己在网上下载,都是比较常见的.

?

2,还原数据库(在附件"keel数据库备份.rar"上)数据库使用的是MS SERVER 2005,

如果更改数据库请添加相应的jar包,和修改db.properties文件.

?

3,部署到tomcat(本人使用的是tomcat5.0)

?

4,启动tomcat,浏览器输入,如http://localhost:8080/keel_jdbc1.0/??(端口自己按实际情况更改)

?

5,帐号,密码都为(admin)

版本 V1.0

1:前台界面暂时只有登录,后续版本会增加复杂的页面!(用Extjs已经3年)

2:后台主要如下

一,通过一个servlet作为前后台交互入口,代码如下:
