Hi Tilman,

this is what I get:

[JPG, jpg, bmp, BMP, gif, GIF, WBMP, png, PNG, wbmp, jpeg, JPEG]
Then it's really not there... JBIG2 is also missing. I'd suspect some problem with your build... try 
- do a clean build
- verify that your pom is ok re: syntax
- run the tool both in and outside of your IDE
- have a look what is in your manifest / in your class path, i.e. what is really there? Look in the directories. You can look at jar files with any zip tool, e.g. 7zip. 
- post the fill pom file.

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

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.
