Tomitribe supports a lot of clients that use ActiveMQ and JMS in production. This post introduces you to both ActiveMQ and JMS. If you already understand the fundamental concepts behind JMS messaging, skip ahead to “A Short ActiveMQ and JMS Tutorial”. It should take five minutes or less.

Jakarta EE: A New Hope

By Community, Jakarta EE, Open Source No Comments

It was announced today that we in the Jakarta EE community would not be able to modify the javax namespace. When I heard that statement uttered for the first time, I was certain I heard wrong. I asked several questions hoping for more positive news with better options in the future. No, it was exactly what I heard. Many of you know me as a positive voice in the community, but even my calm demeanor was cracked. Several visceral statements left my mouth and at one point during the meeting I recall using the word asinine. Transitioning through the stages…

Docker y debug de Apache Tomcat y TomEE

By Apache TomEE, Docker, ES, Open Source, Tomcat, TomEE No Comments

El debug remoto es una práctica común para investigación de problemas de microservicios. Si estas utilizando contenedores Docker Apache Tomcat o Apache TomEE, en la web puedes encontrar varias técnicas como lo son: 1. Extender una imagen oficial y personalizar[1] 2. Utilizar personalización extensiva de CATALINA_OPTS[2] Sin embargo ambos enfoques requieren extra pasos aplicables para algunos escenarios. A continuación les comparto la forma más sencilla que he utilizado para poder hacer debug remoto en Apache Tomcat y Apache TomEE: $ $ docker run -it -p 8080:8080 -p 8000:8000 -e CATALINA_OPTS=”-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:8000″ tomcat:9.0.17-jre11 Anatomía de las opciones utilizadas: docker run Comando para…

Surviving the Frequency of Open Source Vulnerabilities

By Community, Open Source, TomEE No Comments
If you think your company is immune to cyber attacks, think again. By some estimates, nearly half of all websites have, at this very moment, a critical security vulnerability and nine out of ten have at least a moderate security vulnerability.1 No One Is Safe Even the largest and most sophisticated sites are not fully secure. It’s estimated that of the 500 busiest websites one third are not secure including sites like ESPN.com, BBC.com, Wikia.com, MyShopify.com, Chegg.com, and NBA.com1. Within the last year, some of the largest companies in the world have experienced breaches exposing sensitive data and affecting millions...

It’s Easy! Your First TomEE Pull-Request: Fetch, Code, Commit, and Push

By Community, Open Source, TomEE No Comments

This is the second installment in a two-part article covering the Process Task portion of the Contribution Workflow. The Contribution Workflow is covered in detail in the first part within “Section 1: The Contribution Workflow Overview.” The Process Task portion of the Contribution Workflow is where you do the work on an issue (bug fixes, enhancements, tests, documentation) after getting assigned a JIRA ticket. This is where the rubber meets the road; where the actual work of writing or coding a solution takes place. The following diagram shows how the Process Task portion of the Contribution Workflow fits into the…

TomEE for Every Day!

By Apache TomEE, Community, Open Source No Comments

The “TomEE for the Holidays” campaign ended on January 16th of this year. It was great to see so many new Contributors (close to 50) join the TomEE project. In addition, participation from veteran contributors skyrocketed resulting in a level of communication and collaboration that would make any open source community proud. With the success of the “TomEE for the Holidays” initiative, the question became obvious: “How can we (Tomitribe) maintain a high level of participation and comradery in the project?” There were many things that made “TomEE for the Holidays” a success. Encouraging people new to open source to…

It’s Easy! The Anatomy of a JIRA Issue

By Apache TomEE, Community, Open Source No Comments

One of things that I had to learn about when joining the TomEE open source project was JIRA. JIRA is an issue tracking system with some light project management. It’s a great tool for keeping track of who is working on what and what bugs or issues need to be addressed. Note: JIRA isn’t an acronym it’s a truncation of the word, Gojira which is the real Japanese name for Godzilla. The folks that created JIRA chose the name as a tongue-in-cheek jab at their biggest rival at the time, Bugzilla. When you join the TomEE community you will end…

It’s Easy! Get the TomEE Source Code and Join the Community

By Apache TomEE, Open Source No Comments

One of the greatest joys of my life has been working in Open Source. Why? First, I get to work on exactly what I want when I want. Software development is a creative process and working for someone else doesn’t always let me express myself. I need that. If my contributions are helpful, in line with the project’s goals, and are approved by my peers I can make a difference. That brings me to the second thing I love about open source: The people. Every project is different but in the TomEE project, everyone is volunteering their efforts and time…
