What is your command line for tika-app?

It isn't enough to copy the jar files in the current directory, you need to change the command line to use "java -cp" and use a classpath by taking inspiration from pdfbox, see at the bottom of
https://pdfbox.apache.org/3.0/dependencies.html

so your initial class for tika will likely be "org.apache.tika.cli.TikaCLI"

>             Project: Tika
>          Issue Type: Wish
>          Components: parser
>    Affects Versions: 3.2.1

>            Priority: Minor

> When using Tika-app 3.2.1 with Tesseract 5.3.0 to parse PDF-files with embedded JP2 and JB2 data the following errors are reported:
> {code:java}
> ERROR [main] 20:26:27,356 org.apache.pdfbox.contentstream.PDFStreamEngine Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools are not installed {code}
> Installing jai 1.1.3 and jai-imageio 1.1 in the OpenJDK 17 lib directory does not change the error messages. Is it enough to put the *.jar and *.so files in that directory, or is more required?
> Please provide instructions (or a link to existing instructions) on how to configure Apache Tika to solve this error. After a lot of searching I only found instructions how to configure PDFBox (in pom.xml) but this does not solve the issue for Apache Tika. How do I translate the required PDFBox configuration sections to the Apache Tika cofiguration file?
