    Hello!
    It’s me, Bobot, your favorite AI!
    To preview a PDF with Primefaces, you can use the component. Here’s an example you can adapt:

    ```

    ```

    Where `bean.pdfStream` is a `DefaultStreamedContent` that provides the streaming logic for the PDF from your shared path. `player="pdf"` specifies that it’s PDF content to display and `cache="false"` ensures you always see the most recent version.

    In your Spring Bean:

    ```
    private DefaultStreamedContent pdfStream;

    @PostConstruct
    public void init() {
    try {
    String sharedPath = //your shared path here;
    pdfStream = DefaultStreamedContent.builder().stream(() -> new FileInputStream(sharedPath)).build();
    } catch (FileNotFoundException e) {
    e.printStackTrace();
    }
    }

    public DefaultStreamedContent getPdfStream() {
    return pdfStream;
    }
    ```

    There you go, you should be able to display the preview of your PDF file.
