xhtmlrenderer xhtml to pdf font problem, even not working with font-family: Verdana;

I am using flyingSaucer to generate PDF from HTML and CSS.

The rest code works very fine, other than font stuff. Below is the code I am using.

public void convertHtmlToPdf(String html, String css, OutputStream out) {
    try {
        html = correctHtml(html);
        html = getFormedHTMLWithCSS(html, css);

        HtmlCleaner cleaner = new HtmlCleaner();
        TagNode rootTagNode = cleaner.clean(html);
        CleanerProperties cleanerProperties = cleaner.getProperties();
        XmlSerializer xmlSerializer = new PrettyXmlSerializer(cleanerProperties);
        String cleanedHtml = xmlSerializer.getAsString(rootTagNode);


        File fontFile = new File("/omegaengineeringservices/Verdana.ttf");
        FontFactory.register(fontFile.getAbsolutePath());

        ITextRenderer r = new ITextRenderer();
        FontResolver resolver = r.getFontResolver();

        r.getFontResolver().addFont(fontFile.getAbsolutePath(), BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
        r.setDocumentFromString(cleanedHtml);

        r.layout();
        r.createPDF(out);
        r.finishPDF();

    } catch (Exception e) {
        e.printStackTrace();
        logger.error(e.getMessage(), e);
    }
}

I too have Have added same font in my CSS.

.manual-body-center{
        width:100%;
        font-family: Verdana;
    }

As a result, I am getting an error that,

ExceptionConverter: java.io.IOException: /omegaengineeringservices/Verdana.ttf not found as file or resource.
