这是一个学习线程的非常棒的例子。TaskBean类是我们自己的任务，计算1+2+...+100,它实现了Runnable, Serializable 接口，可以作为线程和bean运行。

　　 start.jsp页面负责构造bean和线程对象，并启动线程实行任务然后转到status.jsp显示进度条。

　　 stop.jsp停止任务。 -　　

　 This is a great learning thread example. TaskBean is our own task, computing 1+2+...+ 100, it implements the Runnable, Serializable interface can be run as threads and bean.

start.jsp page bean and the thread is responsible for the target structure and the implementation of the task and then start the thread to show the progress bar status.jsp.

Stop.jsp stop task.
