慈勤强的JFolder1.0版代码(JSP)-林网博客

这个版本主要是兼容了Unix、Linux等操作系统，真正的不再受系统平台的限制。
在0.9测试版发布以后，很多朋友都给了我很好的意见和建议，
对于日常的应用，这个版本应该足够了
在下一个版本中，会增加更多的功能。
在此感谢 Boris von Loesch,古典Lam,CitySuSu等人的帮助

一、功能说明
 jsp 版本的文件管理器，通过该程序可以远程管理服务器上的文件系统，您可以新建、修改、
删除、下载文件和目录。对于windows系统，还提供了命令行窗口的功能，可以运行一些程序，类似
与windows的cmd。

二、测试
 请大家在使用过程中，有任何问题，意见或者建议都可以给我留言，以便使这个程序更加完善和稳定，
留言地址为：http://blog.csdn.net/cqq/archive/2004/11/14/181728.aspx

三、更新记录
 2004.11.29 V1.0测试版发布，修正了Linux系统上的一些问题，在Linux系统上也可以使用。
 2004.11.15 V0.9测试版发布，增加了一些基本的功能，文件编辑、复制、删除、下载、上传以及新建文件目录功能
 2004.10.27 暂时定为0.6版吧，提供了目录文件浏览功能和 cmd功能
 2004.09.20 第一个jsp 程序就是这个简单的显示目录文件的小程序
