我有一个解决方案，用于将富文本内容从一个文档复制到另一个文档中的MIME。见http://per.lausten.dk/blog/2012/12/xpages-dynamically-updating-rich-text-content-in-a-ckeditor.html。我在应用程序中使用它作为用户在新文档中插入内容模板的方式，并使内容在CKEditor中即时显示。
问题在于内嵌图像不包含在复制中 - 只是对图像临时存储的引用。这意味着图像仅对当前会话中的当前用户可见。所以不是很有用。
如何添加图片？
2013年10月4日更新 我仍然在寻找解决方案。

我终于明白了。它更简单，甚至不涉及MIME。诀窍是修改工作HTML中的图像标签以包含base64编码图像，以便src标签可以使用这种格式（这里以gif为例）：
src="data:image/gif;base64,<base64 encoded image>"
我已经拥有从富文本字段中获取HTML所需的代码（请参阅我的问题中已经提到的my blog post）。所以我需要的是用正确的src格式替换图像src标签，包括base64编码图像。
以下代码获取HTML并浏览每个包含的图像并修改src标记：
String html = this.document.getValue(fieldName).toString();
if (null != html) {
final List<FileRowData> fileRowDataList = document.getEmbeddedImagesList(fieldName);
if (null != fileRowDataList) {
final Matcher matcher = imgRegExp.matcher(html);
while (matcher.find()) {
String src = matcher.group();
final String srcToken = "src=\"";
final int x = src.indexOf(srcToken);
final int y = src.indexOf("\"", x + srcToken.length());
final String srcText = src.substring(x + srcToken.length(), y);
for (FileRowData fileRowData : fileRowDataList) {
final String srcImage = fileRowData.getHref();
final String cidImage = ((AttachmentValueHolder) fileRowData).getCID();
final String typeImage = ((AttachmentValueHolder) fileRowData).getType();
final String persistentName = ((AttachmentValueHolder) fileRowData).getPersistentName();
// Add base 64 image inline (src="data:image/gif;base64,<name>")
if (srcText.endsWith(srcImage)) {
final String newSrc = src.replace(srcText, "data:" + typeImage + ";base64," + getBase64(persistentName));
html = html.replace(src, newSrc);
}
}
}
}
}
这是base64编码图像的getBase64（）方法：
private String getBase64(final String fileName) {
String returnText = "";
try {
BASE64Encoder base64Enc = new BASE64Encoder();
ByteArrayOutputStream output = new ByteArrayOutputStream();
base64Enc.encode(this.getEmbeddedImageStream(fileName), output);
returnText = output.toString();
} catch (NotesException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return returnText;
}

您可以通过DominoDocument.AttachmentValueHolder获取内联图像的句柄，请参阅http://public.dhe.ibm.com/software/dw/lotus/Domino-Designer/JavaDocs/XPagesExtAPI/8.5.2/com/ibm/xsp/model/domino/wrapped/DominoDocument.AttachmentValueHolder.html

如果这适合你，会很好奇。 Notes客户端无法显示内联HTML图像
