Rotate PDFs using iText and org.w3c.dom.Document

Question

i'm working with iText in Java Servlets. I'm fighting with the creation of PDFs from my JSP files. I've seen that is not possible, so i created new servlets which parse a String (my HTML page). Here part of the code:

StringBuffer buffer = getHTMLinBuffer(consulenti, anUser);
DocumentBuilder builder = DocumentBuilderFactory
    .newInstance().newDocumentBuilder();
Document doc = builder.parse(new ByteArrayInputStream(buffer.toString().getBytes("UTF-8")));
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(doc, null);
String fileName = "listaConsulenti.pdf";
String absolutePath = getServletContext().getRealPath("/");
String tempPath = absolutePath + "temp/";
File file = new File(tempPath, fileName);
file.createNewFile();
OutputStream os = new FileOutputStream(file);
renderer.layout();
renderer.createPDF(os);
os.close();

This code works. Now i have to create another PDF which needs to have an A4 page rotated by 90°. Using org.w3c.dom.Document i can't find how to do. There is the possibility to use another Document Class, the com.itextpdf.text.Document which has the rotate() method to rotate it, but using this Document i can't find how to do to parse my String (HTML code)...

Hints?

Answer 1

如果您需要的只是侧面的文档，则可以使用以下方法：

private Document document = new Document(PageSize.A4.rotate());

Answer 2

...i've just found out, that iTextRendere is not part of iText, but of Flying Source. In this link i've seen that the creation of a landscape page is simply done by adding some css to the source (X)HTML:

<style type="text/css"> 
@page{ size: 11.69in 8.27in;}
...
</style>
