Hi,
This is very mysterious. There are similar errors here, it seems to be
jdk related:
https://github.com/haraldk/TwelveMonkeys/issues/201
https://github.com/haraldk/TwelveMonkeys/issues/357
Make sure you have a current jdk version, e.g. the last publicly
available jdk8 version, or jdk12.
Also test without pdfbox, i.e. just try setting up a project with
ImageIO.getImageReadersByFormatName("JPEG2000");
and see what happens.
Re mailing list: make sure you're subscribed. If you can't subscribe,
please tell what you did.

Hi Tilman,
For reasons unknown I can only see your response under markmail.org. A copy of
it can be found below.
I commented out the test scope (i.e. <!-- <scope>test</scope> -->) under the
dependency with groupId com.github.jai-imageio for artifactId jai-imageio-core and
jai-imageio-jpeg2000 in pom.xml files in the following directories:
debugger
parent
pdfbox
tools
This was using the source code in pdfbox-2.0.16-src.zip.
When I run java -Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider -jar
app/target/pdfbox-app-2.0.16.jar PDFToImage testwithimages.pdf, the error
message I receive is:

The IDE is Visual Studio Code running in Windows 10 however the source code and
Java compiler etc (Oracle Java 8) are in Linux (Debian stretch) virtual machine
(VirtualBox). I compiled the source code with mvn clean install from a console
in the virtual machine and also executed it in the same console.

Hi,
No java source code change is needed.
How does your pom.xml look?
What IDE are you using?
Please post the full stack trace. I'm surprised that the log mentions
"com.github.jaiimageio.jpeg2000.impl.J2KImageWriterSpi" but at the same
time claims that the JAI tools are not installed. But
"com.github.jaiimageio.jpeg2000" is the package of the tool on github.

Hi,
Are there any simple instructions for a novice in Java on how to suitably change
the source code of PDFBox to allow it to read PDF documents with images in
JPEG2000 format?
I've tried to change pom.xml under various directories (trial and error) and I
keep getting either of the following errors:
Exception in thread "main" java.util.ServiceConfigurationError:
javax.imageio.spi.ImageWriterSpi: Provider
com.github.jaiimageio.jpeg2000.impl.J2KImageWriterSpi not found
or
SEVERE: Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools
are not installed

Prakash
