view PDF in java application - Embedded - Rendering problem

Hello,

I need to view PDF's in my JAVA application. After some research, setting aside paid components, it seemed to me that the best answer would be this:

Displaying pdf in JavaFX

The colleague suggests using the [PDF.js][2] library running within WebView . I was able to view simple PDFs (where there is only text), but I can not see PDFs with images. It looks like it can not load the contents of the entire file.

Some images:

            System.out.println("Url ->>>>>" + file.toURI().toURL().toString());
            engine.load(file.toURI().toURL().toString());
        } catch (MalformedURLException ex) {
            Logger.getLogger(BrowserShowPdf.class.getName()).log(Level.SEVERE, null, ex);
        } catch (URISyntaxException ex) {
            Logger.getLogger(BrowserShowPdf.class.getName()).log(Level.SEVERE, null, ex);
        }



        StackPane root = new StackPane();
        root.getChildren().add(webView);

        engine.getLoadWorker()
                .stateProperty()
                .addListener((observable, oldValue, newValue) -> {
                    // this pdf file will be opened on application startup
                    if (newValue == Worker.State.SUCCEEDED) {
                        try {
                            // readFileToByteArray() comes from commons-io library
                            byte[] data = FileUtils.readFileToByteArray(new File("D:\Font Awesome Cheatsheet.pdf"));
                            String base64 = Base64.getEncoder().encodeToString(data);
                            // call JS function from Java code
                            engine.executeScript("openFileFromBase64('" + base64 + "')");
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    }
                });

        Scene scene = new Scene(root, 900, 800);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }

}

Some help?

Is there any more practical way to view PDF's within java applications?

Thank you
