About Me
I’ve dedicated this blog to provide you Java quick start tutorials for common enterprise use cases (e.g. PDF & document manipulation, security, file handling etc.) both for Java/Jakarta EE and the Spring ecosystem. In addition, you’ll find posts about Software Craftsmanship, Databases & SPA’s.
There are three general blog post types:
- #HOWTO: Simple quick starts to common problems
- #REVIEW: Reviews of books, video courses, podcasts …
- #WHATIS?: Introduction of a technology, framework, feature …
For nearly every post I’m providing the full source code on GitHub. There you’ll also find step-by-step guides within the README for running the example on your machine with e.g. Docker. Feel free to open an issue if anything is not working as expected!
