        PDDocument pdf = PDDocument.load(new File(filename));
        Writer output = new PrintWriter("pdf.html", "utf-8");
        new PDFDomTree().writeText(pdf, output);
        output.close();

public void convertPdf2Html(File input,Writer out) throws IOException, ParserConfigurationException {
        PDDocument pdf = PDDocument.load(input);
        PDFDomTree tree = new PDFDomTree();
        tree.writeText(pdf,out);
