Download/View pdf files uploaded using filedescriptor

Support
#1

Hi,
I have written the following code to view the pdf file which is uploaded by user:

InputStream inputStream = fileLoader.openStream(event.getItem().getUcUpl());
byte[] buffer = new byte[inputStream.available()];
inputStream.read(buffer);
exportDisplay.show(new ByteArrayDataProvider(buffer),"certificate.pdf", ExportFormat.PDF);

This code works correctly on local but when I deploy on AWS instance it fails to load the pdf. There is no error in logs still unable to fetch the pdf.
Can anyone please suggest here?

Hi,
Thanks for your reply.
I am using 7.2.13 CUBA version.
Regarding AWS: We have deployed war files on Amazon EC2 instance and using tomact 9 to deploy. The filestorage path of work directory of tomcat is also given correctly but still pdf is not loaded.

HI,
Do you have an icon on the blocking of pop-up windows in the browser address bar?
It happens sometimes that pop-up windows are blocked by a browser and you just need to resolve them
