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实现一个信息提示窗口，实现方法：大多数的信息窗口是没有标题栏的，因此信息窗口不能由继承JFrame 类来实现，一种简单的做法是通过继承JWindow 来实现（当然继承Window 类也可以，但一个原则是尽量使用swing 中的界面类）。 　　在加载图信息窗口上的图片时，用到java.awt 包中的MediaTracker 类。使用该类的好处是可以更好地管理程序中要使用的图片，同时还可以保证图片和界面同时显示，避免了窗口显示后很久才显示图片的缺点。 ( Java implementation of an information prompt window method: Most of the information is no title bar of the window, the information window can not be achieved by the inherited class JFrame, a simple approach is to be achieved through inheritance JWindow (of course, the Window class can inherit but a principle is to make use of the interface class swing). When loaded on the chart image information window, use the java.awt package MediaTracker class. The advantage of using this class is that you can better manage the program you want to use the picture, but also can guarantee the picture display and interface simultaneously, avoiding the window a long time to display pictures shortcomings. )
