专门为kettle这款优秀的ETL工具开发的web端管理工具。 kettle作为非常优秀的开源ETL工具得到了非常广泛的使用，一般的使用的都是使用客户端操作管理，但问题是当投入生产环境使用时，动辄上百或几百个job需要管理，这时在使用客户端管理已经很难完成了。我所知道的解决方案有用命令行的调用的，操作麻烦，总之还是很难用啦，还有就是开发web端管理工具，kettle自带了一个web端管理工具，界面极其简陋不说，还很难用，基本无法投入生产环境使用，其他没留意到还有没有较好对众多job进行管理的工具。(A web-side management tool specially developed for kettle, an excellent ETL tool. Kettle as a very excellent open source ETL tool has been widely used, the general use is the use of client operation management, but the problem is that when used in production environment, hundreds or hundreds of jobs need to be managed, when the use of client management has been very difficult to complete. The solution I know has command-line calls, troublesome operation, in short, it is difficult to use, but also the development of web-side management tools, kettle has a web-side management tool, the interface is extremely simple, not to mention, it is also difficult to use, basically can not be put into production environment, other did not notice there is no better. Tools for managing many jobs.)

Java编写实现一个FTP客户端程序，通过该客户端连接指定的服务器。useFtpApplet 类继承了Applet 类，在init()中实现的是此Applet 的初始化，设置布局和背景，建立文本、标签和文本域。 　　Connect()方法使用主机地址、用户名和密码作为参数，建立与主机的连接。使用new 生成新的FtpClient 类实例，使用login()方法登录FTP 服务器，调用showFileContents()方法显示文件内容。 (Java prepared to achieve an FTP client program, through which clients connect to the specified server. useFtpApplet class inherits the Applet class, init () is initialized in the realization of this Applet, set the layout and background, the establishment of the text, labels and text fields. Connect () method uses the host address, user name and password as parameters to establish a connection with the host. Use new FtpClient generate a new instance of the class, using the login () method to log FTP server, call showFileContents () method to display the file contents.)
