How to add a border to a PDF page?

This is a snippet of my source code:

Rectangle rect= new Rectangle(36,108);
rect.enableBorderSide(1);
rect.enableBorderSide(2);
rect.enableBorderSide(4);
rect.enableBorderSide(8);
rect.setBorder(2);
rect.setBorderColor(BaseColor.BLACK);
document.add(rect);

Why am I not able to add border to my PDF page even after enabling borders for all sides? I've set border and its color too still I'm not able to add border.

In iText 7 you will need a few lines of simple code to draw a border of a page:

public void createPdf(String dest) throws IOException {
    // Create a PdfDocument
    PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
    // Create a page
    pdfDoc.addNewPage();
    // Get the dimensions of the page
    float width = pdfDoc.getDefaultPageSize().getWidth();
    float height = pdfDoc.getDefaultPageSize().getHeight();
    // Define a PdfCanvas instance
    PdfCanvas canvas = new PdfCanvas(pdfDoc.getFirstPage());
    // Add a rectangle
    canvas.rectangle(20, 20, width - 40, height - 40);
    canvas.stroke();
    // Close PdfDocument
    pdfDoc.close();
}

Moreover PdfDocument has a getPage(int page) method, so you can get any page you want. Whether you are looking for drawing a border for every page, see the PageBorder example, where we implement the IEventHandler interface and add it to the pdfDoc on the start page event:

pdfDoc.addEventHandler(PdfDocumentEvent.START_PAGE, new PageBorderEventHandler());
