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）！
