File docFile = new File("C:\\test.rtf");
        File outFile = new File("C:\\test2.rtf");
        FileWriter writer=null;
        FileReader reader = null;
        try {
            reader = new FileReader(docFile);
             } catch (FileNotFoundException ex) {
            ex.printStackTrace();
        javax.swing.text.rtf.RTFEditorKit kit = new RTFEditorKit();
       // Document doc = jEditorPane1.getDocument();
        Document doc =  kit.createDefaultDocument();
        try {
            kit.read(reader, doc, 0);
           String text=doc.getText(0,doc.getLength());
           text=text.replaceAll("&nom&","my name");
            //jEditorPane1.setText(doc.getText(0,doc.getLength()));
           jEditorPane1.setText(text);
           writer=new FileWriter(outFile);
           writer.write(text);
           writer.close();
           reader.close();
        } catch (BadLocationException ex) {
            ex.printStackTrace();
