when I try to upload the pdf file the pdf file is uploaded successfully to the system folder. but the upload progress is showing in the waiting stage so the redirection from progress bar to view pdf file not working.

                    request.params(":file_id"),
                    batchId);

    }
}

@Override
public void addRoutes() {
    get(":upload_id/json", new JobStatusJson(), new JsonTransformer());
    get(":upload_id", (req, rsp) -> {
        return "";
    }); // TODO: implement
}

}

return new JobProgress(firstWorkingJob != null ? "working" : "completed", "Dummy message", "", pctComplete, request.params(":file_id"), batchId);

firstWorkingJob= value is never getting null so jobProgress never completed

unable to identify how to complete the job progress

I have checked the same scenario in the ruby project that's working fine.

Hi @dharm18990,

Yes, I never got around to finishing that part. This project (tabula-web-java) is a proof of concept, meant to evaluate whether we should move to Java in our web app.

Of course, we will gladly accept a PR that implements that (it pretty much needs to replicate the JRuby version's behavior).

HI @dharm18990

Did you solve this issue?

I am stuck at this part.

[ClementNerma]

I have the same issue, no error on the server whatsoever.

Hi @ClementNerma, my previous answer: #3 (comment)

I saw your answer, I just added an answer to indicate the problem was still there, I don't know if there has been any update on this / opened PR on this topic?

[jazzido]

No updates, unfortunately. At the moment, all of the projects under the tabulapdf organization are dormant.
