Question

我正在从html转换pdf，其中包括使用ITextRenderer，

的css

    ClassLoader classLoader = DigiFaxInvoice.class.getClassLoader();
          URL url = classLoader.getResource("html file path");
            String urlString = new File(url.getFile()).toURI().toURL().toString();
            String HTML_TO_PDF = "pdf file path";
            OutputStream os = new FileOutputStream(HTML_TO_PDF);       
            ITextRenderer renderer = new ITextRenderer();
            renderer.setDocument(urlString);      
            renderer.layout();
            renderer.createPDF(os);        
            os.close();

我收到了以下错误，

您能否解释一下我收到此错误的原因以及解决方法？
