Apache FOP Console Messages

I am using Fop-0.20.1. to generate PDF. How can i stop FOP from printing
console messages?
Or i could redirect the messages to some file. Plus from which jar i could
get org.apache.log.* classes. The code is given below:

private void generatePdf(File xmlFile, File xslFile, String pdfFileName)
		throws Exception {
		Driver driver = new Driver();
		driver.setRenderer(Driver.RENDER_PDF);
		InputHandler inputHandler = new XSLTInputHandler(xmlFile,
xslFile);
		XMLReader parser = inputHandler.getParser();
		OutputStream pdfOut = new FileOutputStream(pdfFileName);
		driver.setOutputStream(pdfOut);
		driver.setXMLReader(parser);
		driver.render(parser, inputHandler.getInputSource());
		pdfOut.close();
	}
