Hi Maruan,

thank you for your reply. Yes, I already had a look at that page, from that
I took the dependencies I put in the pom I showed in my mail.

I am getting the error even when the suggested dependencies are set.


It's very weird, I use the same dependencies and it works.

Please include

|System.out.println(Arrays.toString(ImageIO.getReaderFormatNa‌​mes()));|

in your code at the start, what do you get?

Tilman




Regards.

Hi all,

I am getting some errors with version 2.0.4. In a small maven project I

set

up, when I try to render a page from a PDF file, I get this in console:

I added the dependencies you suggest (I think) in
https://pdfbox.apache.org/2.0/dependencies.html.

After some debugging I came up with this stack trace:

It is trying to get a reader for "JPEG2000" and can't find it. Am I

missing

something to make it work? or should I think that the pdf file has some
"unusual" image inside it?

Thanks in advance for your help.

Best Regards.
