Build a stand alone java class to take in a URL and save the PDF image returned by the URL

Our Diamond Certificate Laboratory, AGS, has changed the transport mechanism when we retrieve diamond certs.

The URL used to return the content type of 'application/pdf', and then we'd open the URL, load in all the bytes, and save the input stream to a PDF file on the local file system.

Now, I'm seeing the content type as 'application/json' ... and do not know how to open the stream to extract the PDF file.

Here is a sample URL:

[login to view URL]

I'm attaching the existing code. The only thing I changed from the original is the 'content-type' check from 'application/pdf' to 'application/json' and I stopped there.

You only need to handle the redirection returned by the server. I can do it for you. It is not really very hard, it's just a matter of looking carefully at what the server is responding.
