In the previous blog post “An Overview of MicroProfile Configuration” we have seen how to start using MicroProfile Configuration and covered the most common cases where it can be used. In today's blog post, we are going to show you one of the advanced features of MicroProfile Configuration: the ability to add your own ConfigSource.

What if your source of Configuration is somewhere else? Maybe a database or an API? Good news! MicroProfile Configuration allows you to create your…

Last week, the Tenth edition of Jfokus took place in sunny Stockholm, Sweden (really, believe me it was sunny). The conference was three days long, with the first day dedicated to Tutorials and the next couple of days to Conference Sessions. The numbers are impressive. It had over 1700 attendees, making it the second largest Java conference in Europe, right after Devoxx Belgium. Tomitribe was happy to sponsor the event. Literally, every attendee was a Triber with the Jfokus / Tomitribe lanyard. If like me, you don't know what a lanyard is (at least the English word), it's the strap…

A few weeks ago, the Tomitribe team represented by Daniel Cunha and Roberto Cortez had the honour to participate in the first ever SouJava online meeting, hosted by Bruno Sousa and Otávio Santana.

The video is in Portuguese, but if you would like to see something similar in English, please let us know. Enjoy!
