 comment.setText("My comment.");
 builder.getCurrentParagraph().appendChild(comment);

 // ShowInAnnotations is only available in Pdf1.7 and Pdf1.5 formats.
 // In other formats, it will work similarly to Hide.
 doc.getLayoutOptions().setCommentDisplayMode(CommentDisplayMode.SHOW_IN_ANNOTATIONS);

 doc.save(getArtifactsDir() + "Document.ShowCommentsInAnnotations.pdf");

 // Note that it's required to rebuild the document page layout (via Document.UpdatePageLayout() method)
 // after changing the Document.LayoutOptions values.
