Write RTF in RichTextItem from backend

has anyone successfully wrote from a .rtf file to a RichTestItem?

I know how to get the plaintext from a rtf file by using RTFEditorKit

RTFEditorKit kit = new RTFEditorKit();

javax.swing.text.Document doc = kit.createDefaultDocument();

kit.read(fin, doc, 0);

String plainText = doc.getText(0, doc.getLength());

and then just use RTItem.appendText(plainText);

But how do I create the RichTextItem from the RTF file with all the format and Style?

any ideas?

Many thanks in adv
