This blog aims at giving some pointers in order to address the challenge related to the switch from `javax` to `jakarta` namespace. This is one of the biggest changes in Java of the latest 20 years. No doubt. The entire ecosystem is impacted. Not only Java EE or Jakarta EE Application servers, but also libraries of any kind (Jackson, CXF, Hibernate, Spring to name a few). For instance, it took Apache TomEE about a year to convert all the source code and dependencies to the new `jakarta` namespace. This blog is written from the user perspective, because the shift from…

Last year, we announced Apache TomEE as a certified Jakarta EE 9.1 server (See blog post). The season favors gifts and good news, so I thought I would write this small blog to talk about our journey to being MicroProfile 5.0 certified. A while back, Apache TomEE started implementing MicroProfile. At that time, we were contributing to Apache Geronimo implementations for various specifications: config, openapi, opentracing, metrics, health and fault-tolerance. We had our own JWT implementation with additional integration features than what the MicroProfile JWT specification supports. Back then, we were passing the TCK for the MicroProfile 2.1, released October…

Jakarta One 2020, held on December 8th, 2020, gathered industry users and Java communities to share and learn the latest Java enterprise-related technologies. Jakarta EE 9, officially announced in November 2020, that they have created a lot of momentum to keep the conversation going in terms of lessons learned, roadmaps, and best practices. Rafael Guimares, and I, had the opportunity to present the session “Keeping Brazil’s Medical Industry Safe with MicroProfile & JakartaEE”. The session addressed the challenges, opportunities, and roadmap to migrating one of Brazil’s medical industry applications from Java EE into Jakarta EE 9, and MicroProfile implementations, towards…
At the end of February, right before the Covid-19 pandemic shut down all USA conferences, a few Tribers enjoyed the DevNexus week. Watch below a candid 20 minutes video David Blevins and Emily Jiang conversation that shares an insight on topics such as: the upcoming Jakarta Messaging features the Jakarta EE 9 planning the Javax namespace MicroProfile and much more. We hope you enjoy it!

In April 2020, the Bolivia Java User Group held a virtual meetup with Latin American JUG's participants. The event covered Java cloud-native and microservice development, infrastructure, and contribution to the Open Source ecosystem distributed in three sessions: It's Easy! Contributing to Open Source César Hernández, from Guatemala JUG, provided a session about how to contribute and become a valuable part of any open source community. Examples of how to learn and apply soft and hard skills were presented based on MicroProfile and Apache TomEE Open Source projects. Attendees were able to learn how to access and navigate the culture of…

At Oracle Code One 2019 Rafael Guimares, Otavio Santana, and I presented this 45 minutes session for the first time. We provided a case of cloud migration and modernization of a widely use monolithic system with the help of MicroProfile, Jakarta EE, TomEEand Tribestream API Gateway in the Brazilian medical Industry that involved several challenges such as the fifth-largest population and largest territory in the world; technical complexity; and diversity, both geographic and economic. At the beginning of 2020, we were invited via the Jakarta EE Community Forum signed up sheet here to present the session as part of the…

At Tomitribe we are active stakeholders on projects like Apache TomEE, MicroProfile, and JakartaEE and provide Enterprise Support for these and other Open Source projects like Apache Tomcat & Active MQ. In this article, we will cover how developers can create a microservice with Java using the MicroProfile specifications with the DevOps friendly application server, Apache TomEE. If MicroProfile is a topic you want to learn more about, we have many other blog posts covering the basics of MicroProfile with details of each of the specifications along with examples. The official Apache TomEE project website also has a series of…

In our previous blog post, Getting Started with Microprofile Metrics, we covered the basic concepts about metrics scopes and types of application metrics you can include in your existing JAX-RS endpoints. In this article, we are going to summarize the metadata and default values from the MicroProfile Metrics annotations and how they should be applied. The type of annotations applied to a target tracks how that target (field, method, etc.) is measured and the default values help us to make our code cleaner. Default units and targets per annotation Table No.1 describes each of the Metrics annotations and the target…

About a year ago, I wrote a blog post about MicroProfile that explained what it is and why it was created. The explanation of what it is and why it was created is still valuable, but MicroProfle evolves rapidly, so it’s time to talk about where we are at, what’s new, and what to expect in the next few months. MicroProfile Today As per June 2019, MicroProfile 3.0 has been released with the following content. MicroProfile 1.4 release from last year MicroProfile 3.0 release from this year Updated versions of Metrics and Health Check introduced breaking API changes.…

Following up on his last article, “CRUD with TomEE, MicroProfile, and REST”, Hayri Cicek deploys the TomEE MicroProfile application on Heroku, a cloud provider. Heroku is a cloud platform as a service (PaaS) supporting several programming languages and I've been using it for several years without any problems. Visit https://signup.heroku.com/dc and create a free account. TomEE configuration Inside projects root directory create the Procfile and add the following: web: java -DadditionalSystemProperties=-Dhttp.port=$PORT -jar target/blog-exec.jar The Procfile is used to specify commands executed by the app's Heroku containers, which they call "dynos". Dynos are isolated, virtualized Linux containers designed to execute code…
