that's creating a new stream inside the PDF which is a PDF object. That's not the PDF document you are looking for. Write the PDF to a ByteArrayOutputStream like so ByteArrayOutputStream output = new ByteArrayOutputStream(); PDDocument,save(output) byte[] aggregatedReport = output.toByteArray(); BR Maruan > > > > return aggregatedReport; > > > > Martin Lynch | Senior Software Engineer | Kainos | DD: +44 (0)28 9057 1351 | > Fax: +44 (0)28 9057 1101 | [email protected]<mailto:[email protected]> > > > [Sunday > Times]<https://www.kainos.com/kainos-cements-position-sunday-times-top-100-best-companies-work/> > > Follow the Kainos buzz on: Twitter<https://twitter.com/kainossoftware> > Facebook<https://www.facebook.com/KainosSoftware> > Linkedin<http://www.linkedin.com/company/kainos> > Youtube<http://www.youtube.com/user/KainosSoftware> Kainos cements position > sunday times top 100 best companies > work<https://www.kainos.com/kainos-cements-position-sunday-times-top-100-best-companies-work/> > > This e-mail is for the intended addressee only and is strictly confidential; > if you receive it in error please destroy the message and all copies.
