确定莲花多米诺骨牌中哑剧附件的图标(determine the icon for mime attachments in lotus domino)

 我正在使用Lotus Domino的Java-API。 Domino的当前版本是8.5。 我通过DIIOP / CORBA连接到Domino。 我想创建一个带附件的文档（电子邮件）。 该电子邮件是一个多部分MIME文档。 附加文件非常简单，工作完美。 但是，附件会获得一般文档图标（空灰色页面）。 我想为实际内容类型设置一个合适的图标 - 例如.doc文件的单词图标。 这有可能吗？ 我试图修改setContentFromBytes方法的内容类型参数，但无济于事。 
 
 这是一个示例代码： 
 
session.setConvertMIME(false);

File file = new File("c:\\temp\\file.docx");
MIMEEntity child = document.createChildEntity();
MIMEHeader header = child.createHeader("Content-Disposition");
header.setHeaderVal("attachment; filename=" + file.getName());

header = child.createHeader("Content-ID");
header.setHeaderVal(file.getName());

Stream stream = session.createStream();
stream.open(file.getAbsolutePath(), "binary");
child.setContentFromBytes(stream,"application/vnd.openxmlformats-officedocument.wordprocessingml.document", MIMEEntity.ENC_IDENTITY_BINARY);
child.encodeContent(MIMEEntity.ENC_BASE64);
stream.close();
stream.truncate();

// other code here...

session.setConvertMIME(true);
 
 我也尝试过较旧的“application / msword”内容类型，但它也不起作用。 
 
 任何想法如何设置附件的图标？ 
 
 谢谢！ 

I am using the Java-API for Lotus Domino. Current version of Domino is 8.5. I connect to Domino over DIIOP/CORBA. I want to create a document (email) with attachments. The email is a multipart MIME document. Attaching a file ist quite easy and works perfectly. However the attachment gets a generic document icon (empty gray page). I would like to set an appropriate icon for the actual content type - e.g. a word-icon for a .doc-file. Is this possible in any way? I have tried to modify the content type parameter of the setContentFromBytes-method but to no avail.
 
here's a sample code:
 
session.setConvertMIME(false);

File file = new File("c:\\temp\\file.docx");
MIMEEntity child = document.createChildEntity();
MIMEHeader header = child.createHeader("Content-Disposition");
header.setHeaderVal("attachment; filename=" + file.getName());

header = child.createHeader("Content-ID");
header.setHeaderVal(file.getName());

Stream stream = session.createStream();
stream.open(file.getAbsolutePath(), "binary");
child.setContentFromBytes(stream,"application/vnd.openxmlformats-officedocument.wordprocessingml.document", MIMEEntity.ENC_IDENTITY_BINARY);
child.encodeContent(MIMEEntity.ENC_BASE64);
stream.close();
stream.truncate();

// other code here...

session.setConvertMIME(true);
 
I have also tried the older "application/msword" content type but it also dont work.
 
Any ideas how to set the icon for the attachment?
 
Thanks!
