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).

I thoroughly evaluated this some time ago for my open source invoicing tool (https://github.com/mzinsmeister/klubu). I ended up using headless chromium and selenium plus paged.js (which i injected into the html using selenium). There sadly is no open source java implementation of modern HTML and CSS standards.
I found a project that does exactly that (https://github.com/gotenberg/gotenberg). It’s my best bet for now, but I still need to test GraalVM integration with JS runtimes (and test JS libraries) and the Kotlin compiler targeting Node.
