我需要开发一个 Lotus Notes 插件，将一些 UI 添加到 Lotus Notes 主 UI，并在用户创建和发送电子邮件时执行以下操作：
- 截取外发邮件，查看邮件中是否有附件。
- 如果在电子邮件中发现任何附件，请取消发送电子邮件。
- 处理电子邮件的附件，然后再次发送电子邮件（通过调用一些 Notes API）
这在 Lotus Notes 插件中可行吗？
谢谢和问候， 纳迪姆·乌拉

我认为您可以使用 java lotus notes API 来做到这一点。从这里下载示例.. http://www.nsftools.com/tips/NotesTips.htm#javascraps 下载 javascraps.zip 文件..它有最大 API 的示例..
要完成您的工作，您需要在 Lotus Notes 中创建一个 Java 代理，然后您需要根据您的要求使用 Java API 编写 Java 代码以完成任务。

* The MessageBox class allows you to create simple message boxes
* using only the java.awt classes. All you have to do is create an instance
* of a MessageBox and use it to call the doOkCancelDialog or the
* doInputBox methods. You can use a single MessageBox instance to
* create multiple dialogs.
*
* This class has been implemented here as an inner class, but there's
* no reason why it couldn't be a class all by itself. The functionality to
* create buttons and messageboxes has been modularized, so it should
* be easy for you to add your own methods to this class, or make global
* modifications as you desire.
*
* The only really complicated/weird thing I had to do was to write and
* include the MultiLineLabel class, which is included towards the end
* of this class as an inner class. Read the comments associated with
* that class to see what's going on there.
*
* Make sure you import java.awt.* and java.awt.event.*

* Okay, this is a pain, but java.awt doesn't natively have a Label-type class
* that allows you to display text that's more than one line. So I had to write one
* myself. The class below is a modification of some code from the fantastic
* book, "Java in a Nutshell".
*
* The big change I made was to allow this multi-line label to have a fixed width,
* so the Label wouldn't fly off the screen if you had a big paragraph of text to
* display. The width is specified in "columns", which I defined as the width of
* the letter "X" in whatever font is being used. The text that you add to the label
* is automatically split into chunks that are no longer than the number of columns
* specified (you'll see the code to do this in the parseLabel method).
*
* This sample implementation is an inner class of the MessageBox class, although
* it could also be a separate class all by itself. I made it an inner class to make it
* easier to copy and paste everything from one agent to another.
