Usage of Docling Api in Quarkus App

[GodierLuna]

Hello,

I am looking for any example or help to integrate Docling in my quarkus app.
Would anyone have experience with it?

Best

Hey!

I see we have an extension there: https://github.com/quarkiverse/quarkus-docling .

You don't really need any config to make it run. Just install the extension and it should run. You can follow https://docs.quarkiverse.io/quarkus-docling/dev/getting-started.html. Its actually quite simple.

Thank you for you replies. However, I followed all that documentation and still face 404 errors.

This is my code:

I added the dependency in the pom
Injected the api

  @Inject
    DoclingApi doclingApi;

and use it in this function

private String extractTextAsMarkdown(final byte[] file) throws IOException {

     final DoclingApi.ProcessFileV1alphaConvertFilePostMultipartForm form = new DoclingApi.ProcessFileV1alphaConvertFilePostMultipartForm();

     final Path temp = Files.createTempFile("upload-", ".pdf");
     try (final OutputStream os = Files.newOutputStream(temp, StandardOpenOption.WRITE)) {
         os.write(file);
     } catch (final IOException e) {
         throw new RuntimeException(e);
     }
     final File pdfFile = temp.toFile();

     form.files = List.of(pdfFile);
     form.fromFormats = List.of(InputFormat.PDF);
     form.toFormats = List.of(OutputFormat.MD);
     form.returnAsFile = false;
     form.doOcr = false;
     form.forceOcr = false;

     try {
         return doclingApi.processFileV1alphaConvertFilePost(form).getDocument().getMdContent();
     } catch (final WebApplicationException e) {
         throw new RuntimeException("Failed to convert PDF to Markdown " + e.getMessage(), e);
     }
 }

Any idea what might be missing?

I've created quarkiverse/quarkus-docling#43 where we can continue this discussion. It doesn't really belong here in the main Quarkus discussion thread anymore.

@GodierLuna shall we take the conversation over there?

I would be happy to, thanks!
