Free Cookbook of 166 Java EE Code Examples

By Apache TomEE, Jakarta EE, Java EE, Open Source, TomEE No Comments

Whenever you clone or otherwise download the TomEE GitHub project you get nearly fourteen dozen examples you can review and run to learn more, not just about TomEE, but Java EE in general. The examples are like a free, code-centric cookbook that covers everything from programming a simple Java web application to CDI interceptors, to WebSockets with TLS Security. With 166 coded examples to choose from it seems there is something for everyone. Getting started with TomEE and running its…

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…

It’s Easy! Your First TomEE Pull-Request: Using JIRA

By Apache TomEE, Community, TomEE No Comments

While all open source tools (i.e. GitHub, Maven, Mailing lists, Java IDEs) used by the TomEE open source community are important, the process of identifying and managing the work done on the project is critical to our success. The tool we use for managing work is the TomEE JIRA issue tracking system. Note: If you are not already familiar with JIRA tickets or find them confusing, you should read “It’s Easy! The Anatomy of a JIRA Issue” after reading this article. It will help clarify all the information a typical JIRA Issue addresses. Becoming a part of the TomEE community…

It’s Easy! Debugging with IntelliJ and TomEE

By Apache TomEE, Open Source, TomEE No Comments

In our last post we provided a step-by-step tutorial that explained how to debug Enterprise Java applications on TomEE from the Eclipse IDE. This time we’ll do the same thing but with IntelliJ! I’ve always found debugging Enterprise Java applications to be a challenge, but modern features of the Java Virtual Machine and tools like IntelliJ make it easy. If you are already familiar with IntelliJ but have not debugged a TomEE application, then this will be a quick but useful tutorial. If you are new to IntelliJ or TomEE you’ll find the steps outlined here very easy to follow….

It’s Easy! Remote Debugging with Eclipse and TomEE

By Community, Eclipse Foundation, Open Source, TomEE No Comments

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…
