Error using iTextPDF and xhtmlrenderer, java.lang.NoClassDefFoundError: com/lowagie/text/pdf/PdfTemplate

Question

I am testing ItexPDF with XHTMLRendered to parse a web to a pdf and got this error

java.lang.NoClassDefFoundError: com/lowagie/text/pdf/PdfTemplate
org.docx4j.org.xhtmlrenderer.pdf.ITextRenderer.<init>(ITextRenderer.java:109)
org.docx4j.org.xhtmlrenderer.pdf.ITextRenderer.<init>(ITextRenderer.java:103)

I am using iTextPDF 5.5.7 and xhtmlrendered.1.0. My code:

String File_To_Convert = "http://localhost:8080/index.php";   
 String url = new File(File_To_Convert).toURI().toURL().toString();
 System.out.println(""+url);
 String HTML_TO_PDF = "ConvertedFile.pdf";
OutputStream os = new FileOutputStream(HTML_TO_PDF); 
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(url);      
renderer.layout();
renderer.createPDF(os);        
os.close();`
