Custom ConfigSource with MicroProfile Configuration

By Community, MicroProfile, Open Source No Comments

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. To refresh your memory, MicroProfile Config already ships with a few ConfigSources by default: file, system properties, and environment variables. What if your source of Configuration is somewhere else? Maybe a database or an API? Good news! MicroProfile Configuration allows you to create your…

An Overview of MicroProfile Configuration

By Community, MicroProfile, Open Source One Comment

When we are developing an application, it is usually a good practice to externalize some aspects of the application so we can change its runtime behavior without the need to change the code. This is what we call Configuration. A few examples may include the application language, the currency symbol, the username and password to connect to the database or a system path to store uploaded files. In a Monolithic Architecture, you may get away from Configuration. It is not a big deal to perform a couple more builds to change some parameters. In the Microservices world, it is impossible….

Tweaking Your Skills in Open Source

By Community, Food for thought, Open Source No Comments

As I said in “The Best Thing I Ever Did Was Open Source”, open source is really where my heart is, so I’m grateful to be working on TomEE – even if sporadically – and seeing that project evolve and grow.  Since David Blevins post, “TomEE for the Holidays”, we have seen a serious uptick in the number of contributors, pull requests, and commits to TomEE.  Every new community member has joined with the same simple question, “How can I help!”, and all of them have received a warm welcome and a plentiful todo list. It’s been a while It…

TomEE for the Holidays

By Apache TomEE, Community, Open Source No Comments

If I were to pick a month to brand “Open Source Month”, it would be December. I could list personal reasons for it, such as December 1999 was the first month I ever contributed to Open Source. That happens to be the same month I married Amelia and have often joked, “I’ve been married to them both ever since.” The real reason is December is the month open source heroes are born. December is Your Time to Shine I’ve noticed a pattern of December being a very prolific month for open source contribution. In December 2006 the OpenEJB 3 codebase…

The Best Thing I Ever Did Was Open Source

By Apache TomEE, Community, Jakarta EE, Open Source, Tomitribe No Comments

When I look back on the 25 years since I graduated and entered the market as a professional software engineer, I see a tapestry of accomplishments, failures, joy, frustration, and finally peace.  One accomplishment, in particular, the Co-Founding of OpenEJB with David Blevins, stands at the top of that list. I started out in Open Source working with Mark Flury on EJB-OSS in 1999, which was later renamed JBoss.  Shortly after that experience, I was hired by a company to develop an entirely new Open Source EJB Container system, OpenEJB, which later became an official Apache project. The opportunity to…
