您可以生成显示进入WebSphere Business Events的事件、这些事件触发的动作以及计算这些事件的交互代码块和过滤器。

You can produce reports that show the events that entered WebSphere Business events, the actions that were triggered by the events, and the interaction blocks and filters that evaluated those events.

然后，用户开始与代码交互。

Then, users start to interact with the code.

And we will show you exactly how you can write programs that actually interact with the user in that way.

我们将给大家示范如何,书写代码以及跟用户交互。
