Temp File Creation Error on GAE With PDFBox

[Doug via StackOverflow]

On GAE I am trying to update a PDF with a FDF file using PDFBox (and Jersey).

I have read on how you can't use PDFBox on GAE because certain classes aren't whitelisted. I was hoping that just populating the PDF from the FDF wouldn't cause an issue if none of these classes are called.

I haven't seen a whitelist issue yet but I am getting a "java.lang.SecurityException: Unable to create temporary file"

So I am wondering if there is someway to avoid the FDFDocument creating the temp file?

Code!

package com.somecompany.test.service;

import java.io.File;
import java.io.OutputStream;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.ResponseBuilder;

import org.apache.pdfbox.pdmodel.common.PDStream;
import org.apache.pdfbox.pdmodel.fdf.*;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDDocumentCatalog;
import org.apache.pdfbox.pdmodel.interactive.form.PDAcroForm;

@Path("/pdfboxtest")
public class PDFBoxTest {

    @GET
    @Produces("application/pdf")
    public Response getFile() throws Exception {

        File pdfFile = new File("resources/GenerateFDF.pdf");
        File fdfFile = new File("resources/fdftest.fdf");

        PDDocument pdfDoc = PDDocument.load(pdfFile);
        FDFDocument fdfDoc = FDFDocument.load(fdfFile);

        PDDocumentCatalog docCatalog = pdfDoc.getDocumentCatalog();
        PDAcroForm acroForm = docCatalog.getAcroForm();
        acroForm.setCacheFields(true);
        acroForm.importFDF(fdfDoc);

        PDStream ps = new PDStream(pdfDoc);
        OutputStream outputStream = ps.createOutputStream();

        ResponseBuilder response = Response.ok((Object) outputStream);
        response.header("Content-Disposition",
                "attachment; filename=wellthatworked.pdf");
        return response.build();
    }
}

Full error log!

A fixed version will be available in 1.8.9. However you can already test it now by going here https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox/1.8.9-SNAPSHOT/ (get a jar file from January 30 21:54 or later).

If it works, press the green checkmark or just delete the question. If it doesn't work, please write a comment.

Note that you may get into more trouble, I heard that GAE has other restrictions, see the discussion here.
