Apache PDFBox VS Apache FOP

Are you looking for a way to render PDF's or produce them? If you want to produce PDF's, I've used https://pdfbox.apache.org/ successfully as well as https://itextpdf.com/ (potentially costs money).

If you don't mind using java, you can use the open source Apache PDFBox library

https://pdfbox.apache.org/

It's relatively performant and it's a mature and supported codebase that can accomplish most pdf tasks.

Then, open the pdf_utils/pom.xml file and add a dependency to PDFBox, in the dependencies section:

There are some libraries for Java that can help you create a PDF file such as PDFBox or IText. Here there's a short exaplanation on how to use them.

So, when I started to view the documents, a lot of them simply failed to open. I had to look around for a library that could verify PDF documents. I had some experience with PDFBox in the past, so it seemed to be a good go-to solution. It had no way to verify documents by default, but it could open and parse them and that was enough to filter out the incorrect ones. It felt a little bit strange just to read the whole PDF into the memory to verify if it is correct or not, but hey I needed a simple fix for now and it worked really well.

PDFBox can do this. It’s not part of the CLI but it wouldn’t be too hard to add:

I've served dynamic content directly as PDF with https://xmlgraphics.apache.org/fop/

Java software was sometimes often a particularly bad offender because java made it even easier to do this shit. Here's an example from people that really should have known better.... https://searchcode.com/file/19737045/fop-1.0/src/java/org/apache/fop/fonts/autodetect/WindowsFontDirFinder.java/ - https://xmlgraphics.apache.org/fop/
