Java上的Lotus Notes插件

Question

我需要一些关于在Java上为Lotus Notes编写小部件的帮助。我的问题是：我根据本教程创建了一个插件：Developing a simple plug-in for Lotus Notes

但是没有关于如何编写代码的信息。我也没能用谷歌找到任何东西。更具体地说：

1. 当我在Notes客户端点击一些电子邮件时，我需要获取这个电子邮件地址并在我的小部件上显示它
2. 当我点击某个链接时，我需要在浏览器中打开该链接

谁能帮我举个例子吗？非常感谢！这是我的代码：

/**
 * This sample class demonstrates how to plug-in a new
 * workbench view. The view shows data obtained from the
 * model. The sample creates a dummy model on the fly,
 * but a real implementation would connect to the model
 * available either in this or another plug-in (e.g. the workspace).
 * The view is connected to the model using a content provider.
 * <p>
 * The view uses a label provider to define how model
 * objects should be presented in the view. Each
 * view can present the same model objects using
 * different labels and icons, if needed. Alternatively,
 * a single label provider can be shared between views
 * in order to ensure that objects of the same type are
 * presented in the same way everywhere.
 * <p>
