So, I'm trying to save the pdf report in database using service methode. I saw that there's a way to specify the output of the generated report by calling : pdfOptions.setOutputStream(output). But how can I call my save methode this way?
I saw this post but i'm stack at the persist point
I apreciate any advice
PDFRenderOption pdfOptions = new PDFRenderOption(options);
pdfOptions.setOutputFormat(FORMAT_PDF);
pdfOptions.setOption(IPDFRenderOption.PAGE_OVERFLOW, IPDFRenderOption.OUTPUT_TO_MULTIPLE_PAGES);
pdfOptions.setOutputStream(response.getOutputStream());//opens report on browser
runAndRenderTask.setRenderOption(pdfOptions);
You are streaming the output directly to the client with
pdfOptions.setOutputStream(response.getOutputStream());//opens report on browser
If you do this, your output gets consumed and you'll not be able to save it to the database.
I would use a "tee" like approach, you know, with one input stream and two output streams.
You could write that yourself, our you just use something like the Apache TeeOutputStream .
This could look like this:
OutputStream blobOutputStream = ...; // for writing to the DB as BLOB.
OutputStream teeStream = TeeOutputStream(response.getOutputStream(), blobOutputStream);
pdfOptions.setOutputStream(teeStream);
