利用edtftpj组件实现FTP文件的上传

edtftpj：http://www.enterprisedt.com/products/edtftpj/download.html下载
需求描述：把WEB服务器上一个目录中所有的文件上传到指定ftp服务器的某个目录中。
分析：
在edtftpj中有个FTPClient类，此类可以实现ftp的上传。用到的几个函数说明如下：
1、构造函数 FTPClient(ftp服务器，ftp端口）
2、login(ftp登录账号，ftp密码) //登录ftp服务器
3、chdir("文件夹名") //进入ftp上的某个目录，类似DOS的cd命令
4、setType(FTPTransferType.BINARY) //设置传输类型
5、mkdir("文件夹名") //在ftp当前目录下新建一个目录
问题：
利用此组件在测试过程中，发现当上传含有中文的文件名时会失败（FTPClient认为它不是一个文件，奇怪）！
