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…

If you are wondering what the heck is going on with Java EE and Jakarta EE, watch this awesome 40 minutes video by Triber Jean-Louis Monteiro (@JLouisMonteiro) in collaboration with Jean-Francois James recorded at JNation 2019 in Portugal.
I’m going to try something different in this article. I’m going to use lots of images as a reference for readers. I have not done that before, but I’ve found when I’m learning something new that it can be very helpful. A big hurdle for me personally, as a Java EE developer, is debugging server-side code from an IDE. In this tutorial, I’m going to show you step by step how to set up Eclipse for “remotely” debugging Java EE applications. I put remotely in quotes because in this article you are really running TomEE on the same machine as…

In our last article about Microprofile Fault Tolerance we explained the motivation for this project and the need to provide a few design patterns under the microservice friendly Microprofile spec, namely: Bulkhead – isolate failures in part of the system. Circuit breaker – offer a way to fail fast. Retry – define criteria on when to retry. Fallback – provide an alternative solution for a failed execution. We also presented some of the libraries that implement this Microprofile specification, including the Geronimo Safegard library, the one used on TomEE 7.1. Lets now dive a bit deeper into the spec and…

The Enterprise Java platform has been evolving steadily since 1999 when it was first introduced as Java 2, Enterprise Edition. Today, Enterprise Java is being standardized under the Eclipse Foundation with the new brand, Jakarta EE. Jakarta EE picks up where Java EE 8 left off, but the roadmap going forward will be focused on modern innovations such as microservices, modularity, and, now, NoSQL databases. The JNoSQL project, of which I’m a part, is excited to announce that it will be the first new standardization project to be adopted by Jakarta EE providing a robust and vendor agnostic API that…

Eclipse MicroProfile defines itself as: The MicroProfile is a baseline platform definition that optimizes Enterprise Java for a microservices architecture and delivers application portability across multiple MicroProfile runtimes. -- MicroProfile FAQ Java for Enterprise applications are usually built on two options: Spring Framework and Java EE. Java EE created a set of specifications defined first by Sun Microsystems and then by Oracle through the Java Community Process. Specifications were meant to facilitate vendor agnostic development and deployment. During the last 5 years, the Java EE platform has become stable and mature resulting in less frequent releases. Java EE has also…

I had the privilege of speaking at Open Source North last week (June 15th) about the transition from Java EE to Jakarta EE. The conference was well organized, and in its 4th year, was completely sold out weeks earlier. It was exciting to see so many people from the Twin Cities focused on open source! The presentations were excellent. The presentation "How Much Freedom is too Much?" about Microservices by Kelly Goetsch was packed to the point that there was not even room to stand in the back. It shows how relevant the topic is to folks in the trenches today. I also enjoyed…

There is so much going on with the transition of Java EE from Oracle to the Eclipse Foundation, that it can make your head spin. Java EE is a huge platform, not only in terms of technology, but also in terms of specifications, governance, and marketing. This “Unofficial” state-of-the-union is an attempt to bring people, not intimately familiar with the work being done, up to speed. Obviously, this is subject to change as the transfer of intellectual property from Oracle to Eclipse Foundation, the establishment of a governance model, and the marketing plan are still being defined. Hopefully, however, this…
